Machine health checking controller is still an experimental. Thus, it needs to be disabled by default. Yet, users still need to have a way to enable it and experiment.
Tested in 4.1.0-0.nightly-2019-04-23-223857
Run `oc describe pod machine-api-controllers-885cf46b9-68ldv`, it has 3 containers: controller-manager, machine-controller, nodelink-controller. We don't have machine-heathcheck by default.
The way to enable machine-healthcheck is by creating a feature gate
Then a new machine-api-controllers pod will be created under openshift-machine-api namespace. It has a machine-healthcheck-controller container.
