This changes makes sure that pending requests are terminated if the selector manager thread exits due to exceptions. This includes: 1. completing CompletableFutures that were returned to the caller code 2. cancelling requests that are in flight 3. calling onError on BodySubscribers that may not have been completed Note that step 3 is necessary as certain CompletableFutures, such as those returned by `BodySubscribers.ofInputStream`, complete immediately, the operation being eventually completed when the last bite of the response is read. Completing a completable future that is already completed has no effect, this case is handled by completing the BodySubscriber too.
