Create example on TransportConfig

As it appeared it's not always clear that via TransportConfig client can redefine default cluster transport settings. Create an example in examples module to demonstrate exactly TranspotrConfig settings.

In example it's expected that there will be one node with csutom host and port and be a Seed (alice). And another node (joe) which connects onto Seed host port and listens for regular (non-system) messages. Make sure that msg sent from alice to joe .. is actually received on joe.
