In the pike release we migrated everything to use uwsgi. There is no
need to force everything back to eventlet. This was necessary when pike
was master because in ocata we used eventlet. We don't want to switch
deployment mechanisms in an upgrade. But now that pike is base we don't
need to have any of these since everything is consistent on both sides
of the upgrade.
