This takes over some of the logic in the is_enabled property which
previously checked two things: (1) is the date time-sensitive and
(2) is the date even applicable to this course.
Now, is_enabled is only responsible for time-sensitive checks and
the new is_allowed property checks applicability.
In this way, we can more cleanly separate whether a date block
should show up on the dates sidebar (is_enabled and is_allowed)
and the dates tab (is_allowed).
Created an API to be called by the Outline Tab
in the Course Home MFE. This API currently only
returns Course Tool data. Preemptively using the
`course_home_api/outline/v1/...` naming scheme to
make way for more Outline Tab data within this API.
This endpoint is intended to contain generic information for
every page in the Course Home MFE. It contains course information
for the header (Course title, org, number, key) as well as staff
status for the user and the Course tabs to display.
