Fixes#11800
Type check the value of count so we don't panic on the conversion.
I wondered "why didn't we do this before?" There is no excuse for NOT
doing it at all but the reasoning was beacuse prior to the list/map work
in 0.7, the value couldn't be anything other than a string since any
primitive can turn into a string.
Regardless, we should've always done this.
A security_group_rule can also be created from a `prefix_list_id`.
Introduced in #11809

These are skipped without the SSH_UPLOAD_TEST flag, since they require
connecting to a running ssh server on localhost as the current user, and
one creates a very large file.
* provider/aws: output the log group name when create fails
* adjusted formatting to match other error output
* fixup detailed error message for ResourceAlreadyExistsException
* forgot an import
* show the log group name regardless of error type
Previously the AMI creation accepted a static value for the AMI's block device's volume size.
This change allows the user to omit the `volume_size` attribute, in order to mimic the AWS API behavior, which will use the EBS Volume's size.
Also fixes a potential panic case when setting `iops` on the AMI's block device.
The `aws_ami` resource previously didn't have any acceptance tests, adds two acceptance tests and a full testing suite for the `aws_ami` resource, so further tests can be written, as well as expansion upon the other `aws_ami_*` acceptance tests

During backend initialization, especially during a migration, there is a
chance that an existing state could be overwritten.
Attempt to get a locks when writing the new state. It would be nice to
always have a lock when reading the states, but the recursive structure
of the Meta.Backend config functions makes that quite complex.
* Enable remote s3 state support for assume role
- provide role_arn in backend config to enable assume role
Fixes#8739
* Check for errors after obtaining credentials
