Containers not starting fails on RBAC enabled k8s

When running the OOM scripts on a RBAC enabled kubernetes,
readiness probes failed to check dependencies status as they
don't have the needed access rights.

Note for the reviewer :
 The fix has been tested on a rancher installation (k8s 1.8)
 and on a kubeadm installation (k8s 1.8), but not a previous
 versions of k8s. There might be issues with the command when
 used on pre RBAC (<1.6) versions of k8s. This should be tested
 with such version if early backward compatibility should be a
 concern.
