[ci] Start migrating to zuul v3

This patch migrates 2 jobs install-ubuntu and install-centos. Both these
jobs have an equal playbook, so they are merged now and only job
definitions set the proper node type.

Also, the post playbook for most of rally jobs are added. It is generic
and can remove a bunch of code duplication.
