Banner image URL is exposed on the course list and course details API
endpoints. The new `banner_image_url` API field has both the relative
and absolute URLs for the image it represents, if it is set.
Previously, dismissing one course update would disable all future
updates. But that feels a bit limiting.
Instead, these are the new rules:
- If the newest update has not been dismissed yet, it gets displayed.
- If the newest update has been dismissed, we display nothing.
- Editing the newest update will cause it to be displayed again.
- New updates get displayed, even if previous updates were dismissed.
This commit includes a light refactoring and addition of some utility
methods to help manage the above.
It also notes that the learning MFE does not use the "latest_update"
waffle option, which controls the labeling of the update message.

Some tests were still relying on deprecated
WaffleSwitchNamespace.override method, which was working before because
we were importing WaffleSwitchNamespace from waffle_utils.__init__. This
no longer works after we import WaffleSwitchNamespace from edx-toggles.
Codejail logs all calls to `safe_exec` that include a `slug`.
Provide a `slug` in the Python-safe-exec debug view so that
usages of it are logged (for debugging purposes).
Pasting a longer password than allowed limit silently truncated to the
max value, resulting in creating an account with a password user is
unaware of because no validation error occurs.
