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.
