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

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.
Previously, an `aws_rds_cluster` that contains active instance groups would timeout on a destroy, if the destroy was able to only target the rds_cluster and not include the instance groups.
This would result in a `400` response from AWS, and Terraform would sit in a wait-loop until a 15-minute timeout while waiting for the cluster to be destroyed.
This catches the error returned from the `DeleteDBCluster` function call such that the proper error case can be returned to the user.
`400` from the AWS API:

`TestAccAWSDBEventSubscription_importBasic` is still failing, but has been failing since November.
Discovered after #11619 was fixed, and while fixing acceptance tests for the `aws_spot_instance_request` resource.
Previously the `aws_spot_instance_request` resource wouldn't populate any of the block device attributes from the resulting instance's metadata. This fixes that issue, and also fixes the `aws_spot_instance_request` acceptance tests to be more equipped for running in parallel.

Previously the `root_block_device` config map was a `schema.TypeSet` with an empty `Set` function, and a hard-limit of 1 on the attribute block.
This prevented a user from making any real changes inside the attribute block, thus leaving the user with a `Apply complete!` message, and nothing changed.
The schema API has since been updated, and we can now specify the `root_block_device` as a `schema.TypeList` with `MaxItems` set to `1`. This fixes the issue, and allows the user to update the `aws_instance`'s `root_block_device` attribute, and see changes actually propagate.
Adds tag support to the `aws_dynamodb_table` resource. Also adds a test for the resource, and a test to ensure that the tags are populated correctly from a resource import.

If an `aws_volume_attachment` is identical to one that already exists in
the API, don't attempt to re-create it (which fails), simply act as
though the creation command had already been run and continue.
This allows Terraform to cleanly recover from a situation where a volume
attachment action hangs indefinitely, possibly due to a bad instance
state, requiring manual intervention such as an instance reboot. In such
a situation, Terraform believes the attachment has failed, when in fact
it succeeded after the timeout had expired. On the subsequent retry run,
attempting to re-create the attachment will fail outright, due to the
AttachVolume API call being non-idempotent. This patch implements the
idempotency client-side by matching the (name, vID, iID) tuple.
Note that volume attachments are not assigned an ID by the API.

Fixes: #11549
When a user passes the wrong argument to a route53_record import, they
got a crash. This was because we expected the ID to parse correctly. The
crash looked like this:
```

Error importing: 1 error(s) occurred:
* aws_route53_record.import1: unexpected EOF
panic: runtime error: index out of range
```
Rather than throwing a panic to the user, we should present them with a more useful message that tells them what the error is:
```
% terraform import aws_route53_record.import mike.westredd.com
aws_route53_record.import: Importing from ID "mike.westredd.com"...
