Add default aws API filter based on common standards

[shwdean]

Issue #, if available:

Description of changes:

Classify AWS APIs into read and write based on AWS API naming standards (convention over configuration). This can be permanent or a stop-gap until traits are added to AWS API models.

By default adding AWS bundles will only include read APIs. Write APIs can be included by passing the --include-write-apis option, or by individually allow-listing the operation. Explicitly specified operations will always override convention-based filters.

For reference, here are the results when adding dynamo-db
