Delete Lambda prototype

Prototype the User DELETE lambda. Amplify does not include this functionality, so putting it in a Lambda with the fine-grained API. This currently does not invalidate outstanding tokens nor does it clean up the database.
@claytonwwilson You will want to add the clean up code instead of the deleted stuff in UserDeleter
