Subject: [PATCH] Use HostToContainer mountPropagation

For any host mounts that include /var/lib/kubelet, use HostToContainer
mountPropagation, which avoids creating extra references to mounts in
other containers.

Affects the following resources:
* haproxy-anchor daemonset
* kubernetes-apiserver-anchor daemonset
* kubernetes-controller-manager-anchor daemonset
* kubernetes-scheduler-anchor daemonset
