The VideoBlock `handle_ajax` is allowing NaN values for speed key
and causing videos to not load. Also added a data migration to fix
the data for learners.

PROD-1148

Fixed the studio breadcrumbs to show the current chapter/section name.

BROKER_HEARTBEAT appears to interfere with the celery worker
configuration. If we want to disable or change the heartbeat interval,
It must be from these configuration options.

Just setting --without-heartbeat and/or --heartbeat-interval on the
workers does not fully work. Eg. --without-heartbeat disables sending
heartbeats, but BROKER_HEARTBEAT = 60 means that the connection will get
a 60s heartbeat interval negotiated.

Adding user_has_staff_access to course metadata response.

Provide links for self paced blocks

When self paced blocks don't have a start date set, still provide
a link to the block (noticable on dates side bar at the least).

Add another attribute to CourseOverview to support the Teams tab

Much like we ignore due dates for homework in units for course
staff, we want to not bother them with a banner about being overdue.

We use this value in the client to understand whether or not we should be showing staff-only parts of the UI to the user.
