Update JOBS interface, Renamed Consume -> Run.

Add DYNAMIC declaration of the pipelines. Update Jobs constructor
interface, add FromPipeline method to construct jobs driver (unique)
via the `Declare` RPC call.
Add `Stop` method to gracefully stop all consumers.
Binary heaps `GetMax` to canonical `ExtractMin`.
Other small improvements.
