When running locally, XBlocks which access third-party software no longer
cause server errors.
Because devstack inherits from aws, the HTTPS flag was implicitly set to 'on'.
This meant that XBlocks attempted to use SSL when dealing with third-party
components like LTI. Since SSL is not enabled on devstack, this caused server
errors whenever these features ran.
This is primarily to reduce load on MongoDB, where we've lately
had performance problems that we suspect are caused by very
large course structures being evicted from MongoDB's cache. This
may potentially give us a path to better performance as well,
but that's not the goal of this commit.
Surprisingly, LZ4 seemed to actually run more slowly than zlib
for this. Possibly because of some overhead in the Python
bindings? GZip was also surprisingly slow given that it uses
zlib underneath (something like 5x slower).
Use separate cache backend for caching structures.
Abstract out course structure cache.
add datadog metrics for compressed course structure sizes
Since we're using a different cache background, we don't need to have a cache prefix
Use dummy cache backend for tests.
Fallback to default cache if course_structure_cache doesn't exist.

Also included a note in the requirements file explaining the situation, and what
needs to happen before this can be upgrade properly.
To mark a language as dark-launched, add it to the DARK_LANGUAGES

@jzoldak showed me that setting `USE_I18N = DEBUG` didn't actually accomplish
what I had hoped it would -- changing DEBUG didn't also change USE_I18N.
This pull request accomplishes what I was trying to accomplish, without being
quite so clever about it.
A new modulestore backed by mongo that changes the data format to
facilitate easy versioning, sharing content between courses, and fast
lookup of course structure and Scope.settings data.
Conflicts:
cms/djangoapps/contentstore/tests/test_contentstore.py
DraftModuleStore was originally designed as a mixin, but never used that
way, and with the upcoming changes to use the versioned module store,
never will be. This changes removes a circular dependency between
mongo.py and draft.py.
