Many plays only target a select subset of hosts,
especially oo_first_master for components such
as logging and registry.

This commit limits the scope of most plays to
eliminate unnecessary task execution on node
groups.  This will result in great time
savings for large deployments.

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.

This needs to be in place for crio.

This role only installs and enables iptables, thus
should only be run once.
