etcd runs some actions locally to copy certs from the
CA cert host. This commit ensures that we respect
the end user's intended behavior with become
when using 'anisble_become' in the inventory.

Other roles with similar tasks have been modified
in the same manner.

We shouldn't hard-code become behavior as it can be
unexpected for the end user.

This only currently works in the CI because the CI
passes the '-b' argument on the command line, which
will override the task behavior.

openshift_docker_use_system_container might be passed
in via ini inventory as 'openshift_docker_use_system_container=false'

This condition will be interpreted as a string type, instead of
boolean.

Casting openshift_docker_use_system_container as bool
will achieve the users desired intent.

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.

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.
