TNL-4622

Don't use symlinks to include node_modules

FEDX-25

ECOM-4325

Moves ENABLE_INSTRUCTOR_EMAIL and REQUIRE_COURSE_EMAIL_AUTH from settings files
to admin-accessible configuration models. This allows for the bulk email settings
to be modified without a new AMI deploy. See TNL-4504.

Also updates tests:
    -python tests mock out the new configurations in place of the old settings
    -lettuce test has been moved to bokchoy
        (note that there was some loss of coverage here - the lettuce tests had
        been doing some voodoo to allow for cross-process inspection of emails
        messages being "sent" by the server, from the client! In discussion with
        testeng, this seems outside the realm of a visual acceptance test. So,
        the bokchoy test simply confirm the successful queueing of the message,
        and leaves the validation of sending messages to the relevant unit tests.)
    -bok choy fixture has been added, to replace the settings in acceptance.py
    -lettuce and bok choy databases have been updated to reflect the backend changes

The new default is to have bulk_email disabled, we'll need to call this out in the
next OpenEdx release to ensure administrators enable this feature if needed.

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.

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.

The JWT includes the user email and username, along with details pulled from the original access token (e.g. scope, expiration).

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.
