fail early if ssh open, but cloud-init failed

Ansible is already checking to see if the ssh port 22

properly and ssh will fail w/ {{ remote_user }}
This should catch that error early and fail the entire play

Enable pip cache for disk image builder

Apart from "pip-cache" element we also need to have "stackuser"
element, because that's the default in case the variable is unset, and
we don't want to get rid of that element.

* Move some workarounds out of the openstack-installer role into their
  own role
* Remove the neutron password fix. That was an extremely temporary
  workaround

Take out the removal of python-backports from common locations

The python-backports removal is a temporary workaround, and does not
necessarily apply to all install types. This is the first step in
creating a common workaround that removes the python-backports package.
