Reverts previous behavior of enabling the wheel group (with password) on RHEL 7 and 8 inline with the default configuration from Redhat.
Retains behavior for all other OS's but restores the comments and example config from the default config files.
Essentially this keeps the functionality of the new wheel_config parameter provided by 80a5be316f0606599ed7ac06c656a72b543d5ae3 but restores the original behavior of the module when this parameter isn't used.
