      Description

      Currently, the CheckpointCoordinator injects state into the Executions of each vertex.

      For more file grained recovery, not all executions need state at the same time, and different executions may be scheduled at different points in time with different completed checkpoints.

      Executions should hence be eagerly initialized with their checkpoint state handles.
