Design for OnTerminationPolicy

[Yan Xu <xu...@apple.com>]

Hi all,

So after some discussions on the previous draft for restartable tasks and
considering other feature requests such as to allow frameworks to customize
the behavior when tasks in a task group terminate, we incorporated these
features into one OnTerminationPolicy concept, which governs the executor's
handling of task termination and the agent's handling of executor
termination.

Here is new doc:

Feedback welcome!

Yan
