Add volume state
We need to be able to track the number of times a volume has been
mounted for tmpfs/nfs/etc volumes. As such, we need a mutable
state for volumes. Add one, with the expected update/save methods
in both states.
There is backwards compat here, in that older volumes without a
state will still be accepted.
