Vladimir Kozhukalov 52cd767c84 Cleanup unnecessary files
We recently re-worked all the deployment jobs
so they use `deploy-env` Ansible role which works
for both multi-node and single-node environments.
This means there is no need to have diffrent sets
of scripts for these two cases.

Also when we deploy Openstack components it is better
to have values overrides for different scenarios but
not different sets of scripts. Here we remove unused
deployment scripts which in many cases duplicated
the code base.

We will be cleaning up the code base even further to
provide excelent user experience.
