This change allows for discovery of the control plane IPs. The
motivation behind this is to remove the static IP requirement. The
endpoints are discovered by machined, and passed into OSD as arguments
in order to avoid the need to mount /var/lib/kubelet/pki.

Reading /proc/mounts while simultaneously unmounting mountpoints
prevents unmounting all submounts under /var. This is due to the fact
that /proc/mounts will change as we perform unmounts, and that causes a
read of the file to become inaccurate. We now read /proc/mounts into
memory to get a snapshot of all submounts under /var, and then we
proceed with unmounting them.
This also adds some additional logging that I found to be useful while
debugging this. It also adds logic to skip of DaemonSet managed pods.
