Uninstall playbook for Glusterfs 

Uninstall playbook for Glusterfs

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.

In Ansible 2.2, the include_role directive came into existence as
a Tech Preview. It is still a Tech Preview through Ansible 2.4
(and in current devel branch), but with a noteable change. The
default behavior switched from static: true to static: false
because that functionality moved to the newly introduced
import_role directive (in order to stay consistent with include*
being dynamic in nature and `import* being static in nature).

The dynamic include is considerably more memory intensive as it will
dynamically create a role import for every host in the inventory
list to be used. (Also worth noting, there is at the time of this
writing an object allocation inefficiency in the dynamic include
that can in certain situations amplify this effect considerably)

This change is meant to mitigate the pressure on memory for the
Ansible control host.

We need to evaluate where it makes sense to dynamically include roles
and revert back to dynamic inclusion if and where it makes sense to do
so.

Move openshift_deployment_type check into sanity_check
action plugin.  Remove compatibility for deployment_type.

deployment_type has been deprecated for some time now.

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.

Remove hosted vars from openshift_facts.

The current pattern is causing a bunch of undesired sideffects.
