    [FLINK-8632] [flip6] Introduce generalized asynchronous operation handlers

    ## What is the purpose of the change
    
    The asynchronous operation handlers are the generalization of the SavepointHandlers.
    They consist of a Trigger- and a StatusHandler. The TriggerHandler is used to trigger
    an asynchronous operation. The handler stores the operation future and returns a
    trigger id. The trigger id can be used to query the status of the operation via the
    StatusHandler. Once the operation has completed, the StatusHandler will return the
    result.
    
    This PR is based on #5450.
    
    ## Brief change log
    
    - Introduced `AbstractAsynchronousOperationHandlers` derived from `SavepointHandlers`
    - Reworked `SavepointHandlers` according to `AbstractAsynchronousOperationHandlers` interface
    
    ## Verifying this change
    
    - Added `AbstractAsynchronousOperationHandlersTest`
    - Also tested by `SavepointHandlersTest`
    
    ## 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)
      - The S3 file system connector: (no)
    
    ## Documentation
    
      - Does this pull request introduce a new feature? (no)
      - If yes, how is the feature documented? (not applicable)

    [FLINK-8631] [rest] Add support for generic types to the RestClient
    
    This commit allows the Restclient to receive generic response types. In order
    to do this, the MessageHeaders contain now information about the generic
    type parameters of the response type.
