Maintaining RDO on Fedora has proven to be really hard for multiple reasons:
* new dependencies: some reviews gets stalled for long time.
* curating dependencies with compatible versions was difficult and
almost impossible.
* desynchronized cycle, sometimes, new Fedora has to be released with
an OpenStack release entering phase 2 of support, which means that we
have to update EOLed versions for Fedora without being able to update
it.
This is a very bad idea to try deploying a stable release of OpenStack
on a stable Fedora, as you'll likely need to pin some packages, and
will need to rebuild newer ones.

So Fedora support is now limited to clients with the nice benefit that
you always get latest versions of clients.
Moreover, it makes more sense to focus our effort to have a rock-solid
distribution on EL7.
