Hot Rod access log is broken

The Hot Rod access log is broken in several ways:

Todo:

• remove the thread name
• only print the remote address, without the initial / and the port
• fix the processing time, and print it only once
• print the request time using an appropriate format: [10/Oct/2000:13:55:36 -0700]
• use a nicer logger category instead of the class name of the logger
• print the user principal
