I stay by what I said here, it's much easier but adds one more field to the ClientHandler.

@fclairamb I don't want to force you to accept this PR instead of #312. This is only to demostrate the alternative approach I proposed in #312. I prefer this one for the reasons explained there

Thanks, this code allows me to avoid checking if the property is set for the SFTPGo user every time a transfer connection is opened. I'll be adding this functionality to SFTPGo later today after a final code review
