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

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.

All of these roles call the openshift_facts module but didn't include
the role in their dependencies which can lead to errors in Ansible 2.4.

Fixes https://bugzilla.redhat.com/show_bug.cgi?id=1524102

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.

When a package install/update fails due to network blips or other spotty
availability, retry it. If the failure is a real failure (e.g. package
is really not there) it still fails after 3 tries (Ansible default).

This commit removes any references to versions < 1.5/3.5

We assume the version is always greater than or equal to 1.5/3.5.
