Try to get a bit closer to running Cinder jobs regularly

Add a lot of OpenStack projects to the Zuul config.

Reshuffle some diagnostic output in the sp-init playbook.
Run the (still experimental) jobs on the openstack/cinder project,
not the config one.
Run our git-if-needed tool to apply patches to Cinder, os-brick, etc.
