When a resource has only a single key set, the HCL parser treats that
key as part of the overall set of object keys. This isn't valid since
we expect resources to have exactly two keys. In this scenario, we have
to "unwrap" the keys back into a set of objects.
In this example, principal "AWS": "*" tells IAM that any user in the world can assume that role as long as they know the account ID + role name.
In my testing, "Service": "ec2.amazonaws.com" is sufficiently permissive to allow the instance_profile to work without allowing global accesses.

The simple fix here was to check if the Resource was new (to set the
value the first time) then check it has changed each time
I was able to see from the TF log the following:
```
Config
resource "aws_vpc" "foo" {
cidr_block = "10.10.0.0/16"
}
resource "aws_subnet" "foo" {
cidr_block = "10.10.1.0/24"
vpc_id = "${aws_vpc.foo.id}"
}
resource "aws_instance" "foo" {
ami = "ami-4fccb37f"
instance_type = "m1.small"
subnet_id = "${aws_subnet.foo.id}"
source_dest_check = false
disable_api_termination = true
}
```
No longer caused any Modifying source_dest_check entries in the LOG
* provider/aws: Add docs for Default Route Table
* add new default_route_table_id attribute, test to VPC
* stub
* add warning to docs
* rough implementation
* first test
* update test, add swap test
* fix typo
We con no longer copy an InstanceState via a simple
dereference+assignment because of the mutex which can't be copied. This
adds a set method to properly set all field from another InstanceState,
and take the appropriate locks while doing so.
Fixes#8468
If a user wished to bump the `engine_version` of an RDS instance,
Terraform was not sending `allow_major_version_upgrade` to the API
*unless* that value also changed at the same time. This caused the
following error from RDS API:
```
* aws_db_instance.bar: Error modifying DB Instance
* tf-20160825101420910562798obb: InvalidParameterCombination: The
* AllowMajorVersionUpgrade flag must be present when upgrading to a new
* major version.
status code: 400, request id: 20e36364-6ab0-11e6-b794-51f12f4135f1
```
This change will always send the `allow_major_version_upgrade` flag to
the API when the `engine_version` changes.
This still relies on the user setting the correct value i.e. if they are
upgrading from postgres 0.4.7 -> 9.5.2 then the config will need to set
the `allow_major_version_upgrade` flag to be `true`
