The checklist is long and arduous, and a great idea for complex changes,
but not needed for folks who are simpling routing through a variable to

They made large changes in the callback code in 2.0->2.1

I tested a few tweaks to make this run, but because it's the old v1
version, we're looking at a mostly complete rewrite.  Deleting it
and deciding if we actually valued this output was easier.

We've decided not to re-enable callbacks since all this output is in our
CI/CD and having it in hipchat isn't needed.

[ENT-486] Add `ENTERPRISE_SUPPORT_URL` variable.

This is needed because there is a race condition between the stop and
start of supervisor.  The stop will not wait for all child process to
have shutdown by design because this behavior is needed for lms workers.

This means that when we try to do a stop and start together, and the first process
has not fully stopped, we get a failure in the startup of the second process.

There is no obvious way to deal with this in systemd so dealing with it here
instead.

This is needed so that we can properly build devstacks without passing in any other config.
