Don't allow any user to create courses by default

* Change settings default
* Set `ENABLE_CREATOR_GROUP` to False for devstack
* Set `ENABLE_CREATOR_GROUP` to False for tests

In f095c5fe it was decided to enable
anyone to make courses in Studio by default in order to make things
easier in dev environments. This was before the code was open source.
This default is likely in effect for many Open edX instances, but almost
no one would want this setting outside of development.

Yro/Certificate Signal on Learner Track Upgrade

In production environments, the DiscussionXBlock was generating CSS and
JS asset URLs that pointed to the unminified versions of those bundled
assets. Due to our nginx rules, this would cause the assets to be
served without the long expiration times, forcing the user's browser to
constantly refetch these assets while browsing a course.
