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.

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

[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.

We use S3 for a number of uploads. Boto, by default, includes a auth querystring on the returned URLs. Since these uploads are public, there is no need for this querystring. Additionally, the long length URLs cause problems when API consumers need to store the URLs. This commit resolves this problem by removing the auth querystring.

- Updated to latest versions of boto and django-storages-redux packages
- Added AWS_QUERYSTRING_AUTH setting to remove the querystring values
