    Allow extension of volumes with snapshots for Quobyte driver

    This change lifts an earlier limitation that explicitely did
    not extend a volume if snapshots of that volume exist. This
    limitation was lifted on the glusterfs driver and this change
    mirrors that behaviour but adds using the currently active
    image instead of the base file in case snapshots exist.

    Partial-bug: #1687048
