Fix #110 - peadm::status plan fails with new bolt version

  * previously when getting data after a task is run, we fetched
    the result data.  However, a newer version of bolt changed
    the key name to value and broke this code.  This fixes that
    by fetching the newer key name and failing back to the old
    key name if the value does not exist.
