Jesse Pretorius 2fe78ca4ea Make utility install playbook idempotent
To ensure idempotence we do the following:

1. Ensure that the symlinks are only changed if
   they do not yet exist.
2. Switch the openstack client bash completion to
   be a handler which is executed whenever the
   venv changes or the symlinks change.
