media-session: track nodes we create

Browse source 
Add a method to create a node and track the proxy. We can then
use this to track the params on a node.

Don't listen end enumerate the params in the monitors bbut let the
session do that. Use the collected params from the session to create
endpoints and streams.

Always activate the default stream on alsa nodes to create the
ports and have something we can present to apps.
