[ARTEMIS-1983] STOMP NACK behavior incompatible with 5.x

• Type: Bug

Description

The STOMP 1.1 & 1.2 specifications state:

 NACK is the opposite of ACK. It is used to tell the server that the client did not consume the message. The server can then either send the message to a different client, discard it, or put it in a dead letter queue. The exact behavior is server specific.

Artemis discards the message, but ActiveMQ 5.x makes the message available for redelivery or placement on a DLQ. Artemis' behavior should be compatible with 5.x for migrating clients.
