provider/aws: Add support to `aws_redshift_cluster` for restoring from (#8414) 

snapshot

Fixes #6406

Adds 2 new parameters:

* `snapshot_identifier`
* `snapshot_cluster_identifier`

These will be used to allow the Redshift cluster to be restored from a
pre-existing snapshot. Also makes the redshift username and password
fields optional as these are not required for the snapshot

```

When deploying this, I was able to use config as follows:

```
resource "aws_redshift_cluster" "restore" {
  cluster_identifier = "my-test-restored-cluster"
  snapshot_identifier = "sample-snapshot-for-restore"
  node_type = "dc1.large"
}
```

And it resulted in:

```
