ConnectionInitiator
 Opening a connection to a remote host usually tends to be a time
 consuming process and may take a while to complete. One can monitor and
 control the process of session initialization by means of the
 Future interface.
 
There are several parameters one can use to exert a greater control over the process of session initialization:
A non-null local socket address parameter can be used to bind the socket to a specific local address.
An attachment object can added to the new session's context upon initialization. This object can be used to pass an initial processing state to the protocol handler.
 It is often desirable to be able to react to the completion of a session
 request asynchronously without having to wait for it, blocking the
 current thread of execution. One can optionally provide an implementation
 FutureCallback instance to get notified of events related
 to session requests, such as request completion, cancellation, failure or
 timeout.
