Review comment:
If we add `public Task#getCompletionFuture()` method, we can avoid all
changes in `failExternally/cancelOrFailAndCancelInvokable`.
`failExternally/cancelOrFailAndCancelInvokable` can still be used to trigger
the cancelation but we are interested in the task.run completion at the end
which is a subsequent result of the cancelation.
