If you specify just a bare ID, then the initial application works but
subsequent applications may end up doing bad things, like:
```
-/+ aws_ebs_volume.vol_1
availability_zone: "us-east-1a" => "us-east-1a"
encrypted: "true" => "true"
iops: "" => "<computed>"
kms_key_id: "arn:aws:kms:us-east-1:123456789:key/59faf88b-0912-4cca-8b6c-bd107a6ba8c4" => "59faf88b-0912-4cca-8b6c-bd107a6ba8c4" (forces new resource)
size: "100" => "100"
snapshot_id: "" => "<computed>"
```
Fixes#7423
```

automated_snapshot_retention_period
The default value for `automated_snapshot_retention_period` is 1.
Therefore, it can be included in the `CreateClusterInput` without
needing to check that it is set.
This was actually stopping people from setting the value to 0 (disabling
the snapshots) as there is an issue in `d.GetOk()` evaluating 0 for int
also removed the notion of tags from the redshift security group and
parameter group documentation until that has been implemented
Redshift Cluster CRUD and acceptance tests
Removing the Acceptance test for the Cluster Updates. You cannot delete
a cluster immediately after performing an operation on it. We would need
to add a lot of retry logic to the system to get this test to work
Adding some schema validation for RedShift cluster
Adding the last of the pieces of a first draft of the Redshift work - this is the documentation
