Colin McCabe updated KAFKA-14658:
---------------------------------
Description:
We should not open the ports on the broker until we are ready to accept
traffic. This is a particular concern when in KRaft mode, since in that mode,
we create the SocketServer object earlier in the startup process than when in
ZK mode.
The approach taken in this PR is to defer opening the acceptor port until
Acceptor.start is called. There is one exception to this rule, however: when we
are binding to a random port (that is, binding to "port 0"), we open the port
