A base URL can now be configured which is, potentially, prepended to an
asset URL. This allows a CDN, or caching server, to front static asset
requests, taking load off of the contentstore and speeding up page load
times.
Asset URL generation respects locked vs unlocked assets, and will not
generate links to locked assets that would traverse a CDN (even though
the authorization component of the contentserver middleware wouldn't
allow those links to work anyways).
Query params with a value that starts with /static should have their values converted to the full location.
Query params with a value that does not start with /static should be left unchanged.
This commit updates common/djangoapps.
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.
