Subject: sws: add 'connection-monitor' command support

Using this, the server will output in the protocol log when the
connection gets disconnected and thus we will verify correctly in the
test cases that the connection doesn't get closed prematurely. This is
important for example NTLM to work.

Documentation added to FILEFORMAT, test 503 updated to use this.
