Max Inden f677b40ed7 client/authority-discovery: Throttle DHT requests (#7018)
* client/authority-discovery: Throttle DHT requests

Instead of passing one DHT query for each authority down to the network
every query interval, only pass MAX_IN_FLIGHT_LOOKUPS at a given point
in time, triggering new ones when previous ones return.

* client/authority-discovery/worker/test: Fix wrong constant
