This constructor is the standard default constructor, right? I guess we
don't need to specify this constructor then.
> Introduce SlotID, AllocationID, ResourceProfile

> URL: https://issues.apache.org/jira/browse/FLINK-4373
> Project: Flink
> Issue Type: Sub-task
> Components: Cluster Management
> Reporter: Kurt Young
> Assignee: Kurt Young
>
> For the new version of cluster management, we need some more basic data
> structures:
> * SlotID: Identifier of one single slot located in a task executor
> * AllocationID: Slot allocation identifier, created by the JobManager when
> requesting a slot, constant across re-tries. Used to identify responses by
> the ResourceManager and to identify deployment calls towards the TaskManager
> that was allocated from.
> * ResourceProfile: The resource profile of the desired slot (currently only
> cpu cores and memory are supported
