Bulk Email API

Note: Double check that this API doesn't already exist in another repo.

No REST API currently exists for bulk email operations. The existing bulk_email module provides internal APIs but not RESTful endpoints. These instructor-specific endpoints will provide the first REST API for bulk email functionality.
