[WIP] Fix for aws_rds_cluster resource for creating encrypted cross region clusters

[dselvan]

Fixes #630
Closes #2111

Adds source region parameter to the resource as it is required for creating cross region replica clusters where the source cluster is encrypted.

Having a strange issue with the acceptance test where once I add the second us-east-1 aliased provider to the config, I get the following, even though I can see the cluster in the console.

* aws_rds_cluster_instance.test_instance: DBClusterNotFoundFault: Could not find DB Cluster: tf-aurora-cluster-3524689337135782573
			status code: 404, request id: 947d233f-6edc-4197-ac77-df7444d56921

but if I remove the us-east-1 aliased provider and comment out all the cross region stuff, the instance gets created fine.

@radeksimko any idea on what might be wrong, or who I might be able to reach out to to help troubleshooting this? (both a terraform and go beginner)
