Client to Handle Conversation, Presence and Heartbeats

@chudak,

    I am new to Netty, just trying to get my head around how to model these
communication pattern. Is that a single Netty client with 2 different
handlers ( upstream, downstream )? Is it a single Netty client with multiple
handlers per [UP/DOWN] stream, each responsible for different things, e.g.
heartbeat, presence, consuming messages?

Thank you!
