Jesse Pretorius d0696a90ab 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.

Unfortunately we need to use the openstack client to wait for a compute host
to register, so we add it into the nova venv and implement a change in the
way we do the wait so that openrc/clouds.yaml is only implemented on a single
compute host and the wait task is executed there.

# Note (odyssey4me):
# The policy.json file is currently read continually by the services

# directly to the file read by the service because the new policies
# may not be valid until the service restarts. This is particularly
# important during a major upgrade. We therefore only put the policy
# file in place after the service has been stopped.
