Review comment:
My understanding is that they must be different.
Bootstrap will start and listen on `nifi.bootstrap.listen.port`. It will
then start the main NiFi process and pass an argument that tells that main NiFi
process what port Bootstrap is listening on.
Then when NiFi starts, it will start listening on
`nifi.listener.bootstrap.port`, and send a message to Bootstrap (to the port
bootstrap is listening on, i.e. `nifi.bootstrap.listen.port`) telling it what
this port it started listening on. At this point, each process is listening on
a different port and knows which port the other is listening on to send
commands.
By default these ports are random ephemeral ports, hence this communication
needed to tell each other what the ports the other is listening on. This patch
just makes it so you can optionally specify non-random ports.
