[fix][txn] Allow producer enable send timeout in transaction

[congbobo184]

Motivation

In the actual scenario, because the transaction will timeout, the transaction cannot block sending messages all the time. So we send messages with txn need to throw TimeoutException

Modifications

send messages with txn don't need set producer config .sendTimeout(0, TimeUnit.SECONDS)

Verifying this change

add send messages with txn throw TimeoutException test
