    [FLINK-7528] Create DispatcherRestEndpoint and integrate with Dispatcher

    ## What is the purpose of the change
    
    This commit creates the DispatcherRestEndpoint and integrates it with the
    Dispatcher. The DispatcherRestEndpoint is created in the SessionClusterEntrypoint
    and its address is passed to the Dispatcher such that it can answer the
    requestRestAddress RPC.
    
    ## Brief change log
    
    - Create the `DispatcherRestEndpoint`
    - Start `DispatcherRestEndpoint` in `SessionClusterEntrypoint`
    - Pass in REST address to Dispatcher and JobManager
    - Resolve redirection address by directly ask leader component
    
    ## Verifying this change
    
    Verified manually that the `DispatcherRestEndpoint` is started and reachable (even though it does not serve anything yet).
    
    ## 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 serializers: (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
    
      - Does this pull request introduce a new feature? (no)
      - If yes, how is the feature documented? (not applicable)

    [FLINK-7522] Add termination future to ClusterEntrypoint
    
    The termination future is completed when the ClusterEntrypoint shuts down. This
    allows for easier testing.

    [FLINK-7457] Make Dispatcher highly available
    
    This commit introduces a dispatcher leader election and retrieval service to the
    HighAvailabilityServices. Moreover it adds code such that the Dispatcher now takes
    part in the leader election process using the afore-mentioned services.
    
    Let Dispatcher participate in leader election
    
    Add test for Dispatcher leader election

    [FLINK-7409] [web] Make WebRuntimeMonitor reactive
    
    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.

    [FLINK-7458] Generalize GatewayRetriever for WebRuntimeMonitor
    
    Introduce a generalized GatewayRetriever replacing the JobManagerRetriever. The
    GatewayRetriever fulfills the same purpose as the JobManagerRetriever with the
    ability to retrieve the gateway for an arbitrary endpoint type.

    [FLINK-7459] Generalize Flink's redirection logic
    
    Introduce RedirectHandler which can be extended to add redirection functionality to all
    SimpleInboundChannelHandlers. This allows to share the same functionality across the
    StaticFileServerHandler and the RuntimeMonitorHandlerBase which could now be removed.
    In the future, the AbstractRestHandler will also extend the RedirectHandler.

    [FLINK-7527] [rest] Let AbstractRestHandler extend RedirectHandler
    
    By letting the AbstractRestHandler extend the RedirectHandler, we add redirection
    capabilities to the AbstractRestHandler.
