Zeyi (Rice) Fan 068ff196bd eden: SemiFuture-ify BackingStore::getBlob ... Summary: This diff turns the return type of `BackingStore::getBlob` from `folly::Future` into `folly::SemiFuture` to prevent executor leaks. This also enable us to remove the need of holding `serverThreadPool` from backing stores. ---- **Changes** * `ObjectStore` now needs to hold a `folly::Executor::KeepAlive` that is used to turn `SemiFuture`s it gets from backing stores into `Future`. * Signature changes of the implementations of `BackingStore` class. * For tests, I chose to use `QueuedImmediateExecutor` in place of `UnboundedQueueExecutor` as it will basically execute tasks inline. I'm concerned introducing thread pool executor in tests may turn tests flaky.
