Adds a context-sensitive link to learner documentation from the LMS. The base URL defaults to Open edX learner doc and can be overridden with the base URL for edx.org learner doc.  Also relabels the tab for support from help to support.

Also make sure we set the recommended settings according to
<https://django-debug-toolbar.readthedocs.io/en/stable/installation.html#explicit-setup>

Hooks the pre-existing grades code into our new PersistentSubsectionGrade data
model. Includes test updates, and some minor changes to the data model that
were discovered in testing.

Basic architecture of Maintenance App - SUST-19, SUST-42. Implement Force Publish Course view. SUST-46

Adds ENABLE_SUBSECTION_GRADES_SAVED feature flag to both lms and cms. Also
installs the wiring that will allow robust grades to be used for courses
that enable it. This functionality is still gated by the feature flag
and should not be used until the remaining robust grades work is finished.

This is the first in a series of commits that will retrieve and use data from the catalog API. Part of ECOM-4566.

These changes unify four different approaches to JWT creation, moving the core of the AccessTokenView to a general-purpose JwtBuilder class. This utility class defaults to using the system's JWT configuration, but it will allow overriding of the signing key and audience claim to support those clients which still require this. Part of ECOM-4566.

Replaces settings value.

We need to create a user profile in order for users to be usable. This, coupled with the fact, that edx-platform is the owner of auth information, means these commands belong here.

ECOM-4310

This is slightly more complicated than it should be since we're using
custom authentication middleware (i.e., not Django's standard
middleware class). We have to check that the session auth hash we have
stored is equal to the request's session auth hash (since the stored
hash is a function of the password). Normally this gets handled in
`django.contrib.auth.get_user`, but due to our caching we don't go
through that function, even in the cache miss case.

seq_next, seq_prev, and seq_goto events are all renamed, and maintain
legacy compatibility.

This PR also introduces new EventTransformer framework to shim events
based on name prefix.

[PERF-303] Integer XBlocks/XModules into the static asset pipeline.

This PR, based on hackathon work from Christina/Andy, implements a way to discover all installed XBlocks and XModules and to enumerate their public assets, then pulling them in during the collectstatic phase and hashing them.  In turn, the methods for generating URLs to resources will then returned the hashed name for assets, allowing them to be served from nginx/CDNs, and cached heavily.

These are developer only pages, so can not be seen in production
environment. On devstack, you can access these pages in LMS and
Studio at:

This is the second attempt to enable the Pattern Library. The
first attempt broke Django Templates and didn't work correctly
with right-to-left styling.
