Add priority to repositories in base-image

Now it's possible to add a priority for each repo through
--repo-priority on command line and cfg file as well.

This is need because of the usage of ceph mirror and to force the
images to use ceph packages on that repo.

Test plan:

Docker images build succeeded.
stx-openstack apply succeeded.
