Pedestal style terminate-when

See Early Termination in the Pedestal docs + part of the source

I think this kind of hook is something that's missing from Sieppari right now.

I just saw that there is sieppari.context/terminate, while that's a part of this it still means that Sieppari can't accept any "terminate when ..." style instructions. E.g. we might want to not execute any more interceptors once the :response key is set.

sieppari/src/sieppari/context.cljc

Lines 4 to 14 in 8cf22f7

	(defn terminate
	"Removes all remaining interceptors from context's execution queue.
	This effectively short-circuits execution of Interceptors' :enter
	functions and begins executing the :leave functions.
	Two arity version allows setting the response at the same call."
	([ctx]
	(assoc ctx :queue q/empty-queue))
	([ctx response]
	(-> ctx
	(assoc :queue q/empty-queue)
	(assoc :response response))))
