Make TripleO jobs run not only on master and remove noop-jobs
Make TripleO jobs run not only on master and remove noop-jobs

Until recently TripleO didn't maintain stable branches, but now we
do, so we need the gate jobs to work also on stable/liberty branches.

https://review.openstack.org/#/c/240938/ aimed to enable this, but I
think this constraint is preventing the jobs running, e.g see:
https://review.openstack.org/#/c/245670/

Also, after IRC discussion it was noted that we have a spurious
noop-jobs defined, where check jobs do exist, so remove this.
