Execute service setup against a delegated host using Ansible built-in modules
In order to reduce the packages required to pip install on to the hosts, we allow the service setup to be delegated to a specific host, defaulting to the deploy host. We also switch as many tasks as possible to using the built-in Ansible modules which make use of the shade library. The 'virtualenv' package is now installed appropriately by the openstack_hosts role, so there's no need to install it any more. The 'httplib2' package is a legacy Ansible requirement for the get_url/get_uri module which is no longer needed. The keystone client library is not required any more now that we're using the upstream modules. As there are no required packages left, the task to install them is also removed.
