Martin Cermak 8d5d041590 Include downstream/RHEL tests
Find new home for downstream RHEL tests.  Upstream them.  The set of
tests used for fedora gating stays intact:  The gating tests are only
those having the tier1 tag set in their main.fmf file.  The testplan
plans/ci.fmf filters the others out from gating.

The set of Fedora gating tests stays the same as it was before this
change.
