Review comment:
StreamGraph is exposed anyway because there is
`StreamExecutionEnvironment.getStreamGraph()` though I see it is marked
`@Internal`. I'm fine also with passing the environment.
>IMO any use-case where usage of the StreamGraph is appropriate (for which
tbh there are none as the JobGraph would be a better choice anyway) is already
a pretty low-level thing in which case you can work directly against a
ClusterClient.
So you are suggesting to move the code here to `ClusterClient`? I think that
would make sense.

> RemoteStreamEnvironment.execute doesn't support restore from savepoint,
> though the underlying ClusterClient does. Add an explicit "execute remotely"
> that can be used by downstream projects.
