Title: Make course ids and usage ids opaque to LMS and Studio [partial commit]

This commit adds the non-courseware lms/djangoapps and lms/lib.

These keys are now objects with a limited interface, and the particular
internal representation is managed by the data storage layer (the
modulestore).

For the LMS, there should be no outward-facing changes to the system. The keys
are, for now, a change to internal representation only. For Studio, the new
serialized form of the keys is used in urls, to allow for further migration in
the future.
