Deleting a recordset returns 204 (Deleted) even though it is async

[Vinod Mangalpally]

Deleting a recordset returns 204 (deleted) and not a 202 (pending). This is because the status and action on a delete of a recordset are not set correctly. Even though central tries to set the records to "delete/pending", when it is returned to the api the status/action are set to "active/none"

    Deleting a recordset returns 202

    * Update the recordset's status correctly before deleting it.
    * Deleting a zone now returns 202 with the zone, showing
    the status and action
    * Deleting a recordset now returns 202 with the recordset,
    showing the status and action

    One issue still remains (needs a different fix):
    Deleting a recordset without any records returns 202,
    but the recordset returned shows a status of 'ACTIVE'
    and not 'PENDING'. This is because recordset does
    not have a status field.
