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.

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.

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).

Use ADDTL_MOUNTS to add a bind mount to the etcd configuration.
