openstack-ansible/playbooks/os-nova-install.yml
Andrew Bonney 5f278ee02e Remove service-specific tags from service playbooks 
This removes service-specific tags like 'nova' as they are confusing
in their current state, and only appear useful if run using the
setup-openstack playbook. The tags restrict which pre/post tasks
run, but don't prevent the related roles from running.

This causes issues such as: calling setup-openstack with a
'nova' tag would not run the 'haproxy-service-config' step, and
running os-nova-install with a 'nova-config' tag wouldn't run
HAProxy maintenance steps.
