Allow collectd-openstack tasks to run without a controller

Several errors would occur if you attempted to run this playbook without
a controller group or controller under the controller group.  This commit
resolves both by ensuring each group actually exists and the when statements
in Ansible to short-circuit before attempting to get groups['controller'][0]
