For stream_mode=updates (the default) stream the output of each node as soon as that node finishes
...
- currently output of all nodes is streamed only when all nodes in that step finish
- checkpoint/values stream chunks still yielded only at the end of the step, as they require applying all updates

Merge configurable fields with previous checkpoint config before each run ( #510 )
...
* Merge configurable fields with previous checkpoint config.
* Update update_state() and aupdate_state() to merge configurable fields with previous checkpoint config.
* Update tests to verify that all checkpoint metadata contain the expected configurable field keys. This assertion is needed because a run can have an arbitrary number of steps based on the construction of the graph.
