    Add mechanism to update snapshot provider_id

    During the L release we added the ability to store
    provider_id info for volumes and snapshots. We did
    not however add a mechanism for this info to be updated
    on upgrades.

    This patch adds on to the volume update mechanism and
    gives a driver the opportunity to set provider_id columns
    that aren't set on snapshots just as it does for volumes.
