Motivation
The buffer pooling introduced in #292 has a serious bug in that the buffer gets released back to the pool after it's written on the connection. The problem is that, if there's a failure, a message can be written again after the reconnection, in which case we're sending garbage data.
We need to tie the buffer lifecycle of the send request instead and, in that optic, it doesn't make to have the pool on the connection, rather it should be at the partition producer level.
