Add rules to check for a Resource wildcard in a policy

[phelewski]

This should apply for any policy type, just make sure that all resource types are covered.

For example:

• aws_sqs_queue_policy
• aws_sns_topic_policy
• etc...

We might want to considering failing if these resources are using inline rather than a policy document.
aws_iam_policy_document would then have it's own set of rules in a single place.

[kmonihen]

The Terraform documentation recommends using an aws_iam_policy_document data source for several good reasons:

• Native Terraform configuration - no need to worry about JSON formatting or syntax
• Policy layering - create policy documents that combine and/or overwrite other policy documents
• Built-in policy error checking

Need rules for these resources (KMS #96 & Elasticsearch #95 are covered in other issues).
