Revert "Revert "Revert "Stop running manage-projects"""

Now that puppet is being driven centrally with sequencing,
we can let it run manage-projects too. We still don't want
the manage-projects cronjob run - so we'll want to add something
else to do upstream tracking.

This reverts commit aa84680c2a87e2b17b2884ed63a9ba74530cc843
