Subject: [PATCH] Nova: workloads adoption, mariadb pre-/post-checks

* MariaDB pre-/post-checks:

Get services topology specific configuration in
pull_openstack_configuration. Add missing role for that as well.

Split maridb source vs podified env vars shell headers to use it
in corresponding places.

Update and fix the composition of the services pre-check list to
execute it before stopping services.

Update and fix the composition of the list of the services to be
stopped (cannot pull data from stopped services).

Verify no dataplane disruptions during the FFU/adoption process.

Verify Nova services still control pre-created VM workload after
FFU/adotpion is done.

Replace oc run with oc exec in post checks. Fix 'oc rsh' which breaks
expected formatting for 'mysql -rs', when it is called from console vs
called by ansible shell module. Use instead 'oc exec' to keep post
checks working the same way in docs and executed via ansible tests.

* Pre-launch test VM instance in dev env role.

Add a test role for development environment and mention it
in the docs TOC as well.

Defer pingtest until the network adoption done.
Defer cinder volumes until workloads with volumes adoption done.
Defer Nova RBD backend until workloads adoption from ceph to ceph done.

Use a copy of the install_yaml shell script to bootstrap a VM.
We cannot use it via intall_yamls devsetup make target because:
* we need to wrap it with shell/ocp/etc headers
* we need to use bash aliases ref to openstack commands instead of
  direct openstack CLI syntax
* we should avoid SSH-ing to the source cloud VMs (standalone/computes)
  during EDPM adoption
* install_yaml is going to be deprecated anyway
* it's FIP ping test doesn't work and depends on the network adoption
  done
* it's cinder volume/backup/snapshot/attach test doesn't work yet,
  which is OK for this simpe workload adoption case.
