routing+discovery: extract local channel manager

Browse Source 
The policy update logic that resided part in the gossiper and
part in the rpc server is extracted into its own object.

This prepares for additional validation logic to be added for policy
updates that would otherwise make the gossiper heavier.

It is also a small first step towards separation of our own channel data
from the rest of the graph.
