 Review comment:
   This goes back a bit to the discussion on the ML. Remote execution shouldn't be an intrinsic
part of the environment, as regardless of which environment you're using it is still possible
to submit it remotely provided you have the host/port arguments.
   With how this PR sets things up you don't have to change your `getExecutionEnvironment`
call every time you want to change the submission method; instead you only replace the `execute()`
call which imo makes a lot more 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.
