[GitHub] flink pull request #4527: [FLINK-7409] [web] Make WebRuntimeMonitor reactive

GitHub user tillrohrmann opened a pull request:

    https://github.com/apache/flink/pull/4527

    [FLINK-7409] [web] Make WebRuntimeMonitor reactive

    ## What is the purpose of the change
    
    This commit changes the behaviour of the WebRuntimeMonitor to not longer block serving
    threads by waiting on the result of futures. Instead the RequestHandler now returns a
    CompletableFuture<FullHttpResponse> which is written out to the Netty channel upon
    completion. This will improve the performance of our WebRuntimeMonitor.
    
    This PR is based #4492.
    
    ## Brief change log
    
    - Change signature of `RequestHandler#handleRequest`
    - Adapt existing handlers to return async result
    - Adapt test cases
    
    ## Verifying this change
    
    This change is already covered by existing tests, such as the tests contained in `flink-runtime-web`.
    
    ## 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)`: (no)

      - The runtime per-record code paths (performance sensitive): (no)
      - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Yarn/Mesos, ZooKeeper: (no)
    
    ## Documentation

    [FLINK-7381] [web] Decouple WebRuntimeMonitor from ActorGateway
    
    This PR decouples the WebRuntimeMonitor from the ActorGateway by introducing
    the JobManagerGateway interface which can have multiple implementations. This
    is a preliminary step for the integration of the existing WebRuntimeMonitor
    with the Flip-6 JobMaster.
    
    Add time unit for web.timeout
    
    This closes #4492.
