[FLINK-7789][DataStream API] Add handler for Async IO operator timeouts ## What is the purpose of the change *Currently Async IO operator does not provide a mechanism to handle timeouts. This PR fixs the problem by adding an enhanced `AsyncFunction`, named `TimeoutAwareAsyncFunction`.* ## Brief change log - *Add a new interface, `TimeoutAwareAsyncFunction`, which extends the `AsyncFunction`* - *Change `RichAsyncFunction` to implement `TimeoutAwareAsyncFunction` instead of `AsyncFunction`* - *`AsyncWaitOperator` will invoke `TimeoutAwareAsyncFunction#timeout` when `asyncInvoke` times out* ## Verifying this change - *Add tests to `AsyncWaitOperatorTest`* ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): ( no ) - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: ( yes ) - The serializers: ( no ) - The runtime per-record code paths (performance sensitive): ( yes ) - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Yarn/Mesos, ZooKeeper: ( no ) - The S3 file system connector: ( no ) ## Documentation - Does this pull request introduce a new feature?
