Split out k8scontrol oidc patching

Prior to this change, VRRP setup and Dex setup was bundled into the
same k8scontrol-ha function.  However, subclusters will require
Dex *without* VRRP, so this change splits them up, into
a k8scontrol-oidc (used directly by the subcluster) and k8scontrol-ha
(which will inherit from k8scontrol-oidc).

Closes: 182
