This allows ntpd to be disabled in both the privileged
rack and region controllers for use cases where we
do not wish these processes to conflict with ntpd
on the physical host running the containers. This
method as opposed to overriding sysvinit style scripts
and potentially other ways to launch ntpd that may
exist appears to be the safest way to ensure it does
not ever run.
