When #8171 is done, make the facilitator dynamically adjust its `check-
back-in` times, separately for IPv4 and IPv6, in order to keep a desired
proxy capacity.
Let's say that a desired proxy capacity is that an arriving client gets
proxy service with expected waiting time 2 seconds, given the current
client arrival rate. Make a reasonable model of proxy arrival (e.g. a
Poisson process) and tune it so the mean interarrival time is 2 seconds.
Put a minimum of 10 seconds on it so if there are few proxies we don't ask
them to check back in 0 seconds.
Quantize, maybe to one-minute or perhaps geometrically increasing
intervals, so that you can't exactly calculate the current number of
proxies from the polling interval.
