migrate to new deployment mechanism for openshift-ansible

[mulbc]

There is one tasks in the install procedure in which one is told that openshift is installing and this might take up to 20mins.
This is one of the most sensible spots and it is very hard to diagnose what went wrong - if it breaks.

Can we move to a Vagrantfile based on:
https://github.com/openshift/openshift-ansible-contrib/tree/master/vagrant
And then only add the things specific to Heketi?
That way we see the single steps of the Openshift installation.
