The volume_Droplet test was failing from an incorrect fix pushed on Friday. Fixes the failing test.

* provider/aws: output the log group name when create fails

* 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

When ran in parallel the tests `TestAccAwsEcsTaskDefinition_withNetwork` and `TestAccAwsEcsTaskDefinition_withTask` will overlap with each other due to the shared naming of the `iam_role` resource.

An AWS Security Group Rule requires at least one of `cidr_blocks`, `self`, or `source_security_group_id` in order to be successfully created.
If the `aws_security_group_rule` doesn't contain one of these attributes, the AWS API will still return a `200` response, and not report any error in the response.
Example response from the API on a malformed submission:

This previously caused Terraform to wait until the security_group_rule propagated, which never happened due to the silent failure.
The changeset ensures that one of the required attributes are set prior to creating the aws_security_group_rule.
Also catches the error returned from the retry function. Previously the error was ignored, and only logged at the `DEBUG` level.
