Remove last non-taskless meta-depends from
openshift_node role.

Remove variable 'openshift_node_upgrade_in_progress' as
it is no longer used.

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 commit removes the remainder of openshift_node_facts
role.

Remove openshift_clock from meta depends

This commit combines these two roles.  This will
prevent openshift_node_facts from running twice.

This commit adds openshift_clock role to required plays
instead of using meta_depends.

Currently, having openshift_node and openshift_node_upgrade
as two distinct roles has created a duplication across
handlers, templates, and some tasks.

This commit combines the roles to reduce duplication
and bugs encountered by not putting code in both places.

Most of this role's purpose was to set facts.  The vast majority
of these facts were simply redefining user-supplied variables.

This commit also removes various artifacts leftover from
previous versions, as well as variables that seem to be
entirely unused.
