Add api support to let users opt out of email updates

remove UPDATE_LOGIN_USER_ERROR_STATUS_CODE toggle

Python Requirements Update

Feanil/handle pickling failure

Scheduled emails show "unsubscribe" link if waffle switch
`schedules.course_update_show_unsubscribe` is enabled, and
settings.ACE_ENABLED_POLICIES respects `bulk_email_optout`.

API endpoint allows GET/POST requests, which:

* GET asks for confirmation of opt-out
* POST accepts "unsubscribe" or "cancel", where "unsubscribe" creates the
  Optout entry, and "cancel" does nothing.

Fixes flaky tests:

* The resolvers handle users in "bins", which are groups that depend on the user ID.
* The test user ID varies depending on the test order.
* This change ensures that the bin requested matches the user for the test.

create CSM service

The toggle UPDATE_LOGIN_USER_ERROR_STATUS_CODE was added to roll out a
breaking change for `login_user` auth errors to return a 400 rather than
a 200.

This toggle was enabled in Production on 12/5/2019 with seemingly no
adverse affects.
