Fix type field in thread list endpoint

Look for a consistent css class.

Add fields to threads returned by Discussion API thread list endpoint

The former class, while less-flaky, does not always appear. (For example, if cohorts
are being toggled off.) This css class always appears. Initial findings point to
flakiness being a non-issue if we look for this class.

Addressing RTL inconsistencies on Verification process

Adds preferences API and updates users to V1 - fix

The API's type field should come from the CS data's thread_type field,
not its type field, which distinguishes comments from threads.

This commit adds fields that are related to the requesting user's
interaction with the thread (e.g. following).

make edxnotes bok-choy tests chrome-friendly

This eliminates some flakiness related to the loading of the notes page. It also
sets the 'no content' version of that page as a separate page object so testing
that case is more explicit.

Currently, all XBlock/XModule handlers are lumped together in the
same transaction (courseware.module_render:handle_xblock_callback).
This makes it difficult to pinpoint problems with specific handlers.
With this change, the transaction name will now look like:
