Have something that I think should work now that /srv/salt-overlay will
also be persisted to the data PD. Could still afford to factor the
format-and-mount.sh script together with the mount.sh script. Should
maybe remove sanity checking code from kube-push after testing.
Remove mount-pd.sh so that I can replace it with format-and-mount-pd.sh
while maintaining its change history. There's no need to separate them
out into different scripts.
Rename format-and-mount-pd.sh to mount-pd.sh.
Fix bugs - now verified to work!
Remove unnecessary sanity checking of minion health.
