[REV-693] Delete old holdback code

Users were awareded audit certificate recently. Adding logs to verify
that cutoff date for awarding certificate is correct

PROD-978

The type of the attrib object wasn't actually a dict.

Add in-context display name editor for units on the course outline.

It was an internal class that we can't easily compare to. So I'm opting
to just make the xml output be more consistent and ordered.  I was
hoping to avoid this since the order shouldn't matter but the juggling
we have to do to validate the unorderd data is more complication than
it's worth.

Allow certification regenration for existing honor certificates

staff should be able to regenerate certificates for the students
who have already earned the certificate using honor mode

Prod-612

This is a follow up from MST-16, which was commited
in 3858036a.

Changes:
* Enrich course teams_configuration from a plain Dict
  to a custom XBlock field that uses the new TeamsConfig
  wrapper class.
* Remove teams_conf property from course, as the previous
  change made it redundant.
* Update teams_enabled implementation.
* Remove teams_max_size field from course, which is
  no longer semantically correct, as max team size
  is now defined on a teamset level.
* Remove teams_topics in order to discourage use of raw
  teams config dict.
* Add convenience properties teamsets and teamsets_by_id
  to course.
* Allow periods and spaces in teamset IDs to avoid breaking
  existing course teams.

Some parts of the code still use the old raw config data
(identifiable by searching "cleaned_data_old_format"),
which we expect to be slowly factored away as we build
new teams features. MST-40 has been created to remove any
remaining references if necessary.

MST-18

* fix: bokchoy test

* fix: remove pdb break

Parse transcripts json to compare logically.

This is to deal with a special issue in the video descriptor xml output.
The value of the transcript attribute of the video tag is a serialized
json string.  This can have comparison problems in python3 where the order
of the dictionary output is not gauranteed to be the same. So the strings
don't match equally.  We convert the parsed json instead so that the
comparison can be correct.

For TNL-6938
