This allows non-Atomic hosts to be used to install containerized etcd

This commit continues moving plugins into lib_utils.

This commit does not move any plugins for add-on roles
such as logging and metrics.

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.

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.

Remove all uses of openshift.common.admin_binary

Replace with `oc adm`

This commit refactors some duplicate code, removes
usage of set_fact where not needed, and reorganizes
container_runtime role to use include_role.
