Make a new method that can take a local node and run it in a remote pipeline. This basically replaces all functionality of the streams and more. Add 2 examples for exporting a sink and a v4l2 node Make some more things const Cleanups Make it possible to do things when the node needs scheduling. The default node will schedule the local pipeline but the remote node might also schedule the remote pipeline.
