[Prototype] NoOp container message type

[dannimad]

Solves AB#8283
We need a way to catch whenever a batch becomes empty on resubmission. The "NoOp" message type is intended to accomplish that by being sent in case we have offline load enabled and we try tu resubmit an empty batch.
There's still an optimization to be made about just catching the case where the batch "becomes" empty on resubmt instead just "being" empty in the first place.
