Currently, double upgrade process (3.7 -> 3.9)
for control plane attempts to run openshift_version
role twice to set the appropriate values for
upgrading each major version, 3.8 and 3.9.

This commit instructs openshift_version to
only inquire about the proper settings for 3.9,
and hard-sets the appropriate values for 3.8.

This allows a simplification of the
openshift_version role, allowing for easier
debugging.

Determine which host is the etcd CA host

Remove master_ha bool checks

The `assetConfig` is no longer used now that the console is split into
its own pod.

- Remove `assetConfig` on upgrades to 3.9
- Stop writing logging and metrics URLs to assetConfig for 3.9

Most of these checks are no longer applicable to
the tasks on which they are applied.

This commit removes incorrect ha checks to ensure
services are restarted at appropriate times.

This commit continues moving plugins into lib_utils.

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

After remove become:no statements on local_action tasks,
we need to ensure that the proper file permssions are
applied to local temp directories.

This reason for this is that the 'fetch' module
does not use 'become' for the localhost, just the remote
host.

Additionally, users may not wish for the localhost to
become during a fetch.  local_action will execute with
whatever permissions are specified in inventory or via
cli.

This commit removes become:no statements that break
the installer in various ways.
