impl-node: add support for node.force-rate=0

Browse source 
If you set node.force-rate=0, the rate will be forced to the node.rate
denominator.

This makes it possible to autiomatically make the graph switch to the
native rate of the stream by setting this as the default property on
streams.

See #3026
