Cleanup/standardize usage of tags in plays

The numerous tags within the playbook have been condensed
to two potential tags: "$NAMESPACE-config", and "$NAMESPACE".

These tags have been chosen as they are namespaced and cover
the configuration pre-tasks as well as the option to execute
the main playbook from a higher level play. By tagging
everything in the play with "$NAMESPACE" we're ensuring that
everything covered by the playbook has a namespaced tag. Any
place using the "always" tag was left alone as the tasks being
executed must "always" execute whenever the playbook is called.

Notice: The os-swift-setup.yml playbook file has been
removed because it currently serves no purpose. While the
os-swift-sync.yml is no longer being directly called it has been
left as it could be of use to a deployer.
