glusterfs protocol: handshake to log the version of the peer
* As RPC program's name is just used for logging, we now have 'PACKAGE_VERSION' part of the string, which gets logged in client side. * From client, we send the PACKAGE_VERSION in handshake dictionary, which gets logged on serverside handshake. The change doesn't break any compatibility between client or server as it would only enhance the logging part of handshake.
