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

Failing startup if private settings fail to load

Squashing private settings import errors leads to wasted developer time when developers expect settings to be in place, and they aren't. This change only loads private settings if the private.py file exists. If there is an error during the import of that file, the application will not start.
