* provider/aws: Provide the option to skip_destroy on
aws_volume_attachment
When you want to attach and detach pre-existing EBS volumes to an
instance, we would do that as follows:
```
resource "aws_instance" "web" {
ami = "ami-21f78e11"
availability_zone = "us-west-2a"
instance_type = "t1.micro"
tags {
Name = "HelloWorld"
}
}
data "aws_ebs_volume" "ebs_volume" {
filter {
name = "size"
values = ["${aws_ebs_volume.example.size}"]
}
filter {
name = "availability-zone"
values = ["${aws_ebs_volume.example.availability_zone}"]
}
filter {
name = "tag:Name"
values = ["TestVolume"]
}
}
resource "aws_volume_attachment" "ebs_att" {
device_name = "/dev/sdh"
volume_id = "${data.aws_ebs_volume.ebs_volume.id}"
instance_id = "${aws_instance.web.id}"
skip_destroy = true
}
```
The issue here is that when we run a terraform destroy command, the volume tries to get detached from a running instance and goes into a non-responsive state. We would have to force_destroy the volume at that point and risk losing any data on it.
This PR introduces the idea of `skip_destroy` on a volume attachment. tl;dr:
We want the volume to be detached from the instane when the instance itself has been destroyed. This way the normal shut procedures will happen and protect the disk for attachment to another instance

* Update volume_attachment.html.markdown
Fixes#7607
An empty list is a valid value for formatlist which means to just return
an empty list as a result. The logic was somewhat convoluted here so I
cleaned that up a bit too. The function overall can definitely be
cleaned up a lot more but I left it mostly as-is to fix the bug.
Fixes#7975
This changes the InputMode for the CLI to always be:
InputModeProvider | InputModeVar | InputModeVarUnset
Which means:
* Ask for provider variables
* Ask for user variables _that are not already set_
The change is the latter point. Before, we'd only ask for variables if
zero were given. This forces the user to either have no variables set
via the CLI, env vars, tfvars or ALL variables, but no in between. As
reported in #7975, this isn't expected behavior.
The new change makes is so that unset variables are always asked for.
Users can retain the previous behavior by setting `-input=false`. This
would ensure that variables set by external sources cover all cases.
For #9618, we added the ability to ignore old diffs that were computed
and removed (because the ultimate value ended up being the same). This
ended up breaking computed list/set logic.
The correct behavior, as is evident by how the other "skip" logics work,
is to set `ok = true` so that the remainder of the logic can run which
handles stuff such as computed lists and sets.
There are three equivalent forms for expressing "everyone" (including
anonymous) in IAM policies:
- "Principals": "*"
- "Principals": {"AWS": "*"}
- "Principals": {"*": "*"}
The more-constrained syntax used by our aws_iam_policy_document data
source means that the user can only express the latter two of these
directly. However, when returning IAM policies from the API AWS likes to
normalize to the first form, causing unresolvable diffs.
This fixes#9335 by handling the "everyone" case as a special case,
serializing it in JSON as the "*" shorthand form.
This change does *not* address the normalization of hand-written policies
containing such elements. A similar change would need to be made in
the external package github.com/jen20/awspolicyequivalence in order to
avoid the issue for hand-written policies.
`set PATH=%PATH%;C:\terraform` is the old fashioned CMD ways to do which doesn't work in a PowerShell command line.
Moreover, the change made in the CMD console would not be permanent.
The solution proposed here uses .NET Framework’s System.Environment class in PowerShell to properly edit the path.

This will allows us to filter a specific ebs_volume for attachment to an
aws_instance
