Bulk agent operations should return error status code if any sub-operation fails

Conceptually no longer relevant; the team seemed to conclude that "bulk" versions of operations should be treated as a batch of singular operations on a set of resources rather than one operation with 2 steps (resolve resources, then execute sub-operation). Therefore the status code is probably always 200 and to inspect for failures requires actually parsing the Bundle and inspecting the OperationOutcome of each individual operation.
