hs_pow: Rate limited dequeue
This adds a token bucket ratelimiter on the dequeue side
of hs_pow's priority queue. It adds config options and docs
for those options. (HiddenServicePoWQueueRate/Burst)
I'm testing this as a way to limit the overhead of circuit
creation when we're experiencing a flood of rendezvous requests.
