Pure finagle zookeeper client

[Arink Verma]

Hi!

I am applying for "Pure finagle zookeeper client"

I have implemented few zookeeper protocols, as zookeeper codec.

See project finagle-zk[1] at github which is simple zookeeper client which connects to server, fetch session id and negotiate session-time out. And after few pings send close command.

A brief note about zk, working is included in my gsoc proposal[2]. 

I would be nice to more suggestions regarding proposal as well as finagle-zk. :)
