Verified that it is possible to deploy several overclouds. Didn't test for all the other overcloud functionality (networking etc') that all the integration is proper. Verified in python-rdomanager-oscplugin-0.0.10-1.el7ost.noarch.

So far multiple overclouds are not supported.
Though unified CLI should not hard-code the name. This is not urgent bug at the moment since multiple overclouds are coming later on. We will try to include this bug into overall CLI clean-up.
