    snapshot/cli: Fix snapshot status xml output
    
    snap status --xml errors out if a brick is down and
    doesn't have pid. It is handled in the cli of the snap
    status where "N/A" is displayed in such a scenario.
    Handled the same in xml
    
    snap status <snapname> --xml fails as the writer is
    not initialised for the same. Using GF_SNAP_STATUS_TYPE_ITER
    instead of GF_SNAP_STATUS_TYPE_SNAP for all snap's
    status to differentiate between the two scenarios.
    
    Added testcase volume-snapshot-xml.t to check
    all snapshot commands xml outputs
