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:
* neutron-lb-agent daemonset
* neutron-ovs-agent daemonset
* neutron-sriov-agent daemonset (unused mount removed)
* nova-compute daemeonset
