Updating here, so we can track the conversation. There spec outlines 2
options: If a pre-settled message is sent during a tx that the broker can't
handle it should either (in laymans terms):
1. Close the coordinator link.
2. Set the transaction to rollback only.
Given the 2 options I went with 1. Close the coordinator link.
The benefit of 1. is that the client knows the Tx failed early on and can
stop processing it. Robbie mentioned that a long running tx is unlikely and
probably the client already sent everything + the commit.
The benefit of 2. is that the client does not need to re establish the
coordinator link if the tx fails in this scenario. Robbie mentions that
clients may support this option.
