* 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.

Summary: We show "Issue Open Badges" setting in Studio
Course -> Settings -> Advanced Settings, even if the flag
ENABLE_OPENBADGES is set to False. With this commit, it
will only show up in Advanced Settings if ENABLE_OPENBADGES
is set to True.

Refactoring: Use format with named variables

Adding a reviews page to the course and updating the reviews module on the course about page. Removed the existing coursetalk implementation and put it in a fragment, removed the tests as well. Added configuration settings to specify the reviews template as well as the reviews provider. This is all protected by a waffle flag.
