This commit adds a new GraphSources interface that LND requires for graph related read-only queries. As of this commit, the interface is empty but it will be populated over the next couple of commits. We add an implementation of this interface backed by a pointer to a graphdb.ChannelGraph. The infrustructure is put into place so that the GraphSoure provided to LND can be overridden by a caller of the lnd.Main function. By default, LND will satisfy the interface itself via the new `graphsource.DBSource` struct.
