This commit moves some deprecated variable logic
outside of openshift_facts and into role defaults.

We set these variables using facts in init, no need
to duplicate the logic all around the codebase.

Plugin consolidate

Remove some small items from openshift_facts that
don't need to be there.

This commit relocates filter_plugings to lib_utils,
changes the namespacing to prevent unintended use of
older versions that may be present in filter_plugins/
directory on existing installs.

Add lib_utils to meta depends for roles

Also consolidate some plugins into lib_utils from
various other areas.

Update rpm spec, obsolete plugin rpms.

Removing some remaining embedded etcd facts except
for the migration plays.

This commit removes openshift.common.service_type
in favor of openshift_service_type.

This commit also removes r_openshift_excluder_service_type
from plays in favor of using the role's defaults.

With pacemaker removed there is no longer a need for
openshift.master.cluster_method. We only have one option.

Remove hosted vars from openshift_facts.

The current pattern is causing a bunch of undesired sideffects.
