RHEL may need to override some default property inherited from upstream.
This is currently handled in the class_options() function of the latest
machine type, and thus the defaults need to be carried around each time
we add a new RHEL machine.
Override the defaults in a dedicated function to be called by the
latest RHEL machine type.
