Jesse Pretorius 191e0b8660 Eliminate installing pip on host/containers
None of the hosts need pip installed any more. Everything
installed on the host is now a distribution package, and
all pip packages are inside a virtualenv. As such, we make
the final changes to eliminate the installation of pip on
the host.

1. We change the pip_install role settings to only put
   pip.conf down, and not bother installing pip. The
   pip.conf remains necessary to provide any pip installs
   done in venvs with the details of the repo server.
2. We update the utility container playbook so that it
   installs everything into a venv, then symlinks the
   appropriate openstack client binaries to /usr/local/bin
   for convenient access. This is only done for source
   based installs.
3. We update the ceph radosgw keystone setup to make it
   use the appropriate service host, and to make use of
   the correct runtime venv. It also now makes use of
   native ansible modules instead of our own.
