This commit adds in course messaging for three use cases. First,
when the user is not signed in, the user is shown a message that
provides a link to sign in or register. If the user is signed in
but not enrolled, they are given a link to do so. If the user is
enrolled but the course has not yet started, they are shown a
message explaining when the course starts and shown a link (not
yet enabled) to add a reminder to their calendar.

The implementation defines a base message class and extends it
for the course home messages as well as the previously implemented
page level messages.

Don't add groups in experiment configurations twice.

We cleaned out the feature flag and code using these in
https://github.com/edx/edx-platform/pull/5707
but missed the config (I'll go get them in configuration.git later,
when I pull them out of the secure repos, which is where I found them).

Clearing the cache if the site's configuration was removed.
