A role to create S3 bucket with Dynamodb table for Terraform Backend

[abikouo]

• A new role to create S3 bucket with versioning enabled and optionally and create a Dynamodb table with a partition key named 'LockID' with type of String
• Add integration tests for the new role

@abikouo I also noticed that the Jira ticket specified "The role should be able to either accept an existing IAM role to be granted the above permissions or create a new one", which this doesn't currently do. But I'm not sure if that's actually necessary. @gravesm do we think optionally creating a new IAM role for managing terraform state should be part of this role?

Are there reasons we wouldn't want to? IMO an IAM role is going to be the most common way that people will use to handle access to the backend. There's a whole config section in the s3 backend dedicated to assume role functionality. It seems like it should be easy enough for us to create the role, and would make this much more useful.

Small change, otherwise LGTM.
