Standardized requests logging format

Proposed logging format for requests:

For PUT and POST requests:

<HTTP verb> <HTTP relative URL> <HTTP status code> <response content length> - <response time> ms, user <user name in the system> with id <member ID>, request body: <request body>

For other requests (without the request body):

<HTTP verb> <HTTP relative URL> <HTTP status code> <response content length> - <response time> ms, user <user name in the system> with id <member ID>

In case the user is unauthorized, the string "user <user name in the system> with id <member ID>" should be replaces with "unauthorized".
