Add make_course_usage_key method to modulestore

Updated receipt page to use order endpoint

Upgrade flaky for multiprocessing nose support.

MA-1359 &  MA-1457 DiscussionAPI: return response_count for thread GET/POST

Different modulestores create different usage_keys
for the root course block.  This commit introduces
a new method on the modulestore so each store type
can implement its own.

This is required by the new Course Blocks API since
it wants to derive a usage key from a client-supplied
course key.

Implement third party auth ID mapping API
