Description

Currently we have several network components and each of them starts their own TCP server and occupies separate port.

What if we use only 1 port per node and dispatch discovery, communication, rest, time server, etc traffic to proper component?

Goals:

• simplify deployment procedure
• lower resource requirements (less ports, probably, less connections, etc).
• make network IO related code consistent
• fully move it to NIO APIs (discovery uses blocking IO and thread-per connection model).
