> TaskCommunicator
>   // - registerContainerEnd should provide the end reason / possible rename
>   // - get rid of getAddress
>   // - Add methods to support task preemption
>   // - Add a dagStarted notification, along with a payload
> TaskCommunicatorContext
>   // - Consolidate usage of IDs
>   // - Split the heartbeat API to a liveness check and a status update
>   // - Rename and consolidate TaskHeartbeatResponse and TaskHeartbeatRequest
>   // - Fix taskStarted needs to be invoked before launching the actual task.
>   // - Potentially add methods to report availability stats to the scheduler
>   // - Report taskSuccess via a method instead of the heartbeat
>   // - Add methods to signal container / task state changes
>   // - Maybe add book-keeping as a helper library, instead of each impl tracking container to task etc.
>   // - Handling of containres / tasks which no longer exist in the system (formalized interface instead of a shouldDie notification)
