Glauber Costa f5fd6bd714 LSA: export information about size of the throttle queue ...

Also add information about for how long has the oldest been sitting in the
queue. This is part of the backpressure work to allow us to throttle incoming
requests if we won't have memory to process them. Shortages can happen in all
sorts of places, and it is useful when designing and testing the solutions to
know where they are, and how bad they are.

This counter is named for consistency after similar counters from transport/.
