RSS_TIMEOUT was removed in e8ee2978
but missed in lms/envs

ANALYTICS_API_KEY was used to make direct requests to the
ANALYTICS_SERVER_URL which was our original original analytics effort.

We cleaned out the feature flag and code using these in
https://github.com/edx/edx-platform/pull/5707
but missed the config (I'll go get them in configuration.git later,
when I pull them out of the secure repos, which is where I found them).

EDUCATOR-565 | Add POLICY_CHANGE_GRADES_ROUTING_KEY, fix errors in compute_all_grades_for_course circuitry.

PSA was monolothic, now split, with new features, like
a DB-backed partial pipeline. FB OAuth2 version also upped.

Partial pipelines don't get cleared except when necessary.
They persist for special cases like change of browser while
still mid-pipeline (i.e. email validation step).

Refactor, cleanup, and update of a lot of small things as well.

PLEASE NOTE the new `social_auth_partial` table.

- Keeps platform set default of "Audit" to be backwards compatible and not break stuff
- get COURSE_MODE_DEFAULTS from config if set

move tasks into tasks.py

add more logging

Defaults to SUPPORT_SITE_LINK intentionally.
Also fixed surrounding quality tests, and overall
quality improvements.

LEARNER-1103

Add Enterprise sidebar to login and registration views; remove unneeded fields; make registration form more narrow

This makes it possible to refer to multiple book from a single app.

This also means that Open edX branches will be able to pass bok-choy
tests (at least if the books have already been built.)

This reverts commit 65f13dde.

This reverts commit 88dd85ca, reversing
changes made to bf8aef33.

Although we are phasing out our support of OIDC, this particular feature will allow us to eliminate many of the settings we
share across services. Instead of reading various endpoints and secret keys from settings or hardcoded values, services
with the proper authentication backend can simply read (and cache) the information from this endpoint.
