Netty: Support to bind on multiple host/port pairs

This patch allows to create several netty bootstrap, each of which
listening on different ports. This will potentially allow for features
to listen to different network interfaces for node-to-node or node-to-client
communication and is also the base to listen to several interfaces, so that those
can be used to speed up cluster communication in the future.

Closes #8098
Test: Fix netty multiport tests

Ensuring, that even in local mode, netty is started appropriately.
