    [FLINK-9911][JM] Use SlotPoolGateway to call failAllocation

    ## What is the purpose of the change
    Since the SlotPool is an actor, we must use the SlotPoolGateway to interact with
    the SlotPool. Otherwise, we might risk an inconsistent state since there are
    multiple threads modifying the component.
    This PR is based on #6385.

    [FLINK-9908][scheduling] Do not cancel individual scheduling future
    Since the individual scheduling futures contain logic to release the slot if it cannot
    be assigned to the Execution, we must not cancel them. Otherwise we might risk that
    slots are not returned to the SlotPool leaving it in an inconsistent state.

    [FLINK-9909][core] ConjunctFuture does not cancel input futures
    If a ConjunctFuture is cancelled, then it won't cancel all of its input
    futures automatically. If the users needs this behaviour then he has to
    implement it explicitly. The reason for this change is that an implicit
    cancellation can have unwanted side effects, because all of the cancelled
    input futures' producers won't be executed.

    [hotfix] Replace check state condition in Execution#tryAssignResource with if check
    Instead of risking an IllegalStateException it is better to check that the
    taskManagerLocationFuture has not been completed yet. If, then we also reject
    the assignment of the LogicalSlot to the Execution. That way, we don't risk
    that we don't release the slot in case of an exception in

    [FLINK-9910][scheduling] Execution#scheduleForeExecution does not cancel slot future
    In order to properly give back an allocated slot to the SlotPool, one must not complete
    the result future of Execution#allocateAndAssignSlotForExecution. This commit changes
    behaviour in Execution#scheduleForExecution accordingly.
