Use remote to join nodes on remote graphs

Browse source 
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.
