HTTP latch that aggregates 2 latches, any latch can deny a request.

The latches are asked in order, latch0, latch1, and the first denial is the decision. Latches after a denial are not asked, but every latch observes the final decision with observe-decision, even when an earlier latch fails to observe it. The first failure is returned.
