KAFKA-5595: Ensure client connection ids are not reused too quickly
When there are broker delays that cause a response to take longer than
`connections.max.idle.ms`, connections may be closed by the broker (as well as
by the client) before the response is processed.
If the port is reused, broker may send the outstanding response to a new
connection with the reused port. The new connection will end up with
correlation id mismatch, requiring process restart. This is also a security
exposure since clients receive response intended for the wrong connection.
