Moved request handling from chunk writing to piping for both upstream and unstructured audit requests (structured audit request is the same); turned off request unstructured auditing for all gateway requests with a "GET" method since request has not attachment, to avoid request pipe socket (with end: false option set) 'socket hang up' error; Updated logging messages; changed 'proxy_client' variable name to be 'proxy_clientReq'; changed 'proxyRes' variable name to be 'proxy_Res'; updated headersSent response time log-level from error to info level; added 'finished' events to write streams and 'close' events to request sockets; added 'socket.destroy()' call to callback method for timeout event for both structured and unstructured audit service sockets.
Updated package.json version number.
