Previously `ModifyInstanceAttribute` permissions were required on creating a new instance with an unmodified `source_dest_check` attribute, as we forced the `ModifyInstanceAttribute` set on a new AWS instance.
This change only calls `ModifyInstanceAttribute` if `source_dest_check` was changed from default on a new instance, or if `source_dest_check` was modified.

For `ROLE`s who have been delegated `CREATEDB` privileges and are not a
superuser, in order for them to `CREATE DATABASE` they need to be a member
of the `ROLE` who will be `OWNER` for the new database. Once the
`CREATE DATABASE` is complete, `REVOKE` the `GRANT` that was given to role
so that the user who ran the `CREATE DATABASE` looses all privileges to the
target database (unless of course they're a superuser).

* Delegated DBA ROLEs can now fix OWNER drift for PostgreSQL databases.
Uses the helper functions introduced in #11452
Fixes a panic where specifying a nil `target_arn` for a `dead_letter_config` inside the `aws_lambda_function` resource would throw a panic.
Now, we return a nice error to the user instead of throwing a panic and stacktrace.

A while back `atlas_artifact` was switched from being a `resource` to a `data` provider. When you use the examples suggested in the Terraform Enterprise docs, the Terraform cli shows a deprecation warning and provides an old url to the new data provider docs.
There are some complimentary doc updates in the Terraform Enterprise/Atlas repo.
* vendor: Updating Gophercloud for OpenStack Provider
* provider/openstack: Enable Security Group Updates
This commit enables security group names and descriptions to
be updated without causing a recreate.
* Exposing moid value from vm resource
moid value is needed by NSX resources, like security tag, when we attached security tags to a VMs, so needed before we commit NSX provider.
* fixing gofmt issue
* Updating docs regarding new exported moid attribute.
* Add namespcace ID attribute
This commit also introduce `id` comouted value which is numeric value
used by GitLab to iteract with repository. This should simplify use of
`gitlab_project_hook` usage and would allow to introduce other resources
as described in #14471
* Fixes requested by @richardc
* Handle optional `namespace_id`
* vendor: Update go-gitlab to master@e6c11e
Update go-gitlab to master@e6c11e. This brings in UpdateGroup in
addition to fuller management of other attributes.
* provider/gitlab: Add `gitlab_group` resource
This adds a gitlab_group resource.
This combined with #14483 will allow you to create projects in a
group.
* provider/gitlab: add `gitlab_deploy_key`
Here we extend the gitlab provider further by adding a `gitlab_deploy_key`
resource. This resource allows management of a projects deploy
keys.
* provider/gitlab: Do not test `gitlab_deploy_key` `can_push`
Here we remove the testing of the `can_push` attribute. This makes the
tests less comprehensive, but will allow them to work with the current
release of gitlab-ce.
This change is staged as a distinct commit so it can be easily
dropped/reverted once gitlab MR !11607 has reached a released state.

When a cluster was originally created, you could not enable snapshotting
on it. An error message like this was found:
```

```
There is no guidance from AWS on which is the preferred Cluster in the RG to use for snapshotting. Therefore, I decided to set it to be the first cluster. We can now enable snapshotting

Prior to Terraform 0.7, lists in Terraform were just a shallow abstraction
on top of strings with a magic delimiter between items. Wrapping a single
string in brackets in the configuration was Terraform's prompt that it
needed to split the string on that delimiter during interpolation.
In 0.7, when first-class lists were added, this convention was preserved
by flattening lists-of-lists by one level when they were encountered in
configuration. However, there was an oversight in that change where it
did not correctly handle the case where the inner list was unknown.
In #14135 we removed some code that was flattening partially-unknown lists
into fully-unknown (untyped) values. This inadvertently exposed the missed
case from the previous paragraph, causing issues for list-wrapped splat
expressions with unknown members. While this worked fine for resources,
due to some fixup done inside helper/schema, this did not work for other
interpolation contexts such as module blocks.
Various attempts to fix this up and restore the flattening behavior
selectively were unsuccessful, due to a proliferation of assumptions all
over the core code that would be too risky to change just to fix this bug.
This change, then, takes the different approach of removing the
requirement that splats be presented inside list brackets. This
requirement didn't make much sense anymore anyway, since no other
list-returning expression had this constraint and so the rest of Terraform
was already successfully dealing with both cases.
This leaves us with two different scenarios:
- For resource arguments, existing normalization code in helper/schema
does its own flattening that preserves compatibility with the common
practice of using bracketed splats. This change proves this with a test
within the "test" provider that exercises the whole Terraform core and
helper/schema stack that assigns bracketed splats to list and set
attributes.
- For arguments in other blocks, such as in module callsites, the
interpolator's own flattening behavior applies to known lists,
preserving compatibility with configurations from before
partially-computed splats were possible, but those wishing to use
partially-computed splats are required to drop the surrounding brackets.
This is less concerning because this scenario was introduced only in
0.9.5, so the scope for breakage is limited to those who adopted this
new feature quickly after upgrading.
As of this commit, the recommendation is to stop using brackets around
splats but the old form continues to be supported for backward
compatibility. In a future _major_ version of Terraform we will probably
phase out this legacy form to improve consistency, but for now both
forms are acceptable at the expense of some (pre-existing) weird behavior
when _actual_ lists-of-lists are used.
This addresses #14521 by officially adopting the suggested workaround of
dropping the brackets around the splat. However, it doesn't yet allow
passing of a partially-unknown list between modules: that still violates
assumptions in Terraform's core, so for the moment partially-unknown lists
work only within a _single_ interpolation expression, and cannot be
passed around between expressions. Until more holistic work is done to
improve Terraform's type handling, passing a partially-unknown splat
through to a module will result in a fully-unknown list emerging on
the other side, just as was the case before #14135; this change just
addresses the fact that this was failing with an error in 0.9.5.

Instead of using a hardcoded version prerelease string, which makes release automation difficult, set the version prerelease string from an environment variable via the go linker tool during compile time.
The environment variable `TF_RELEASE` should only be set via the `make bin` target, and thus leaves the version prerelease string unset. Otherwise, when running a local compile of terraform via the `make dev` makefile target, the version prerelease string is set to `"dev"`, as usual.
This also requires some changes to both the circonus and postgresql providers, as they directly used the `VersionPrerelease` constant. We now simply call the `VersionString()` function, which returns the proper interpolated version string with the prerelease string populated correctly.
`TF_RELEASE` is unset:

During an instance shut-down network interfaces may be detached during the `READ` method of a Terraform run.
This protects the case where a network interface was detached, and is now `nil` at the time of the Terraform run, fixing nil pointer dereferences.
This commit catches an error when the instance is parsing and building
its network list. This can happen when a cloud provider responds with
a non-JSON response for the list of networks.
Previously lightsail was limited to `us-east-1` only. This restriction has now been lifted to new regions.

The tests did pass, but that was because they only tested part of the changes. By using the `schema.TestResourceDataRaw` function the schema and config are better tested and so they pointed out a problem with the schema of the Chef provisioner.
The `Elem` fields did not have a `*schema.Schema` but a `schema.Schema` and in an `Elem` schema only the `Type` field may (and must) be set. Any other fields like `Optional` are not allowed here.
Next to fixing that problem I also did a little refactoring and cleaning up. Mainly making the `ProvisionerS` private (`provisioner`) and removing the deprecated fields.
1. Migrate `chef` provisioner to `schema.Provisioner`:
* `chef.Provisioner` structure was renamed to `ProvisionerS`and now it's decoded from `schema.ResourceData` instead of `terraform.ResourceConfig` using simple copy-paste-based solution;
* Added simple schema without any validation yet.
2. Support `ValidateFunc` validate function : implemented in `file` and `chef` provisioners.
The previous JSON validator that we were using for IAM policy documents wouldn't catch AWS IAM Policy errors.
The supplied policy document would pass our validator, then fail with the following API error:
```
* aws_iam_role_policy.foo: Error putting IAM role policy tf_test_policy_ymw7hbil9w: MalformedPolicyDocument: The policy failed legacy parsing
status code: 400, request id: e7615d90-3c99-11e7-babc-c14e741605bf
```
This happens if the Policy Document doesn't start with the opening JSON bracket, and often happens in the following case:
```
policy = <<EOF
{
"Version": "2012-10-17",
"Statement": [
{
...
}
]
}
EOF
```
Where, when using a HEREDOC, the policy document is indented incorrectly.
The new validation function for the IAM policies verifies that the first character of the supplied policy document is the leading JSON bracket, prior to validating the JSON string.

When a `google_compute_disk` is attached to a `google_compute_instance`,
deleting can be tricky. GCP doesn't allow disks that are attached to
instances to be deleted. Normally, this is fine; the instance depends on
the disk, so by the time the disk is deleted, the instance should
already be gone.
However, some reports have cropped up (#8667) that deleting disks is
failing because they're still attached to instances. Though this
shouldn't happen, it appears it can happen under some unknown
conditions.
This PR adds logic that will attempt to detach disks from any instances
they're attached to before deleting the disks, adding another safeguard
that should prevent this behaviour.
