Add a way to abort in flight checkpoints

    Details

      Description

      Currently, a started checkpoint alignment can only be dissolved if a newer checkpoint comes, or an input becomes closed.

      To cleanly signal downstream tasks that a checkpoint will not be completed, we need to introduce CancellationBarriers that can be injected into the stream and dissolve a pending stream alignment and notify the task that a pending checkpoint was skipped.
