Server: Stagger checker runs when creating clients
To avoid checkers for all clients all running at the same time
periodically, schedule every initially scheduled future checker to run
at a time in the future a random amount of the interval, from the
current time.
* mandos (Client.init_checker): Schedule the first scheduled future
run of a checker to be a randomly chosen amount of this client's
"interval" (instead of a full interval).
