Updated styling for basic capa problems (multiple choice, dropdown, checkboxes, numerical input and text input) including support for mobile app experience.
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.

Extends the common capa response types (string, numeric, multiple
choice, checkbox, dropdown) with feedback and hint
capabilities. "Feedback" refers to feedback shown to the student when
they check the problem, looking at their specific answer. "Hints"
refers to a Hint button in LMS which the student can click at any time
to see hints for that problem. The implementation extends the markdown
syntax to include feedback and hints. There are new Feedback-and-Hint
specific templates in Studio when the author clicks to add a new
problem.
Caches all permissions per user per course. Adds caching functionality to has_permission and replaces all instances of cached_has_permission with has_permission.
only require ccx-keys once
get_current_ccx will now expect a CourseKey instance as its argument, and will raise a value error if this expectation is not met.
