> SlotManager determines whether a resource can be allocated by the return value of ResourceActions.allocateResource. It can reduce unnecessary waiting by quickly marking the slotRequest as a failure if the resource cannot be allocated.
> The new declareResourceNeed function will not return whether resources could be allocated. This will cause useless waiting for SlotRequests.
> Currently, ResourceActions does only two kinds of things.
> allocate/release resource by ResourceManager, this only supported by ActiveResourceManager
> notify resource not enough to JobMaster
> So we can split ResourceNotEnoughNotifier from ResourceActions, and make ResourceActions only works for ActiveResourceManager
> ResourceNotEnoughNotifier only send notifyNotEnoughResourcesAvailable to JobMaster
> ResourceActions will deal with declareResourcesNeeded
>     For StandaloneResourceManager, The SlotManager will not have one ResourceAllocator, so it can fail the SlotRequests quickly.
