> This issue has two parts:
>  # Support transportation layer connection timeout described in KIP-601
>  # Optimize the logic for NetworkClient.leastLoadedNode()
> Changes:
>  # Added a new common client configuration parameter socket.connection.setup.timeout.ms to the NetworkClient. Handle potential transportation layer timeout using the same approach as it handling potential request timeout.
>  # When no connected channel exists, leastLoadedNode() will now provide a disconnected node that has the least number of failed attempts. 
>  # ClusterConnectionStates will keep the connecting node ids. Now it also has several new public methods to provide per connection relavant data.
