Subject: [PATCH] feat(kube-system): Add readiness probe to quorum
This patch adds a readinessProbe to the quorum pods, this causes the
kubelet to test the etcd health endpoint, resulting in proper status of
the etcd node, and therefore keeping the quorum. This should help to
improve cluster stablility.
