Move channel manager into node state

[eddyashton]

Another part of #2775. The forwarder and node-to-node channels were owned by the enclave and passed to node state, but the enclave doesn't do anything with them. It makes more sense for them to be owned and constructed within the node state. To make that construction path a little cleaner, the ConsensusType in the configuration moves from the top-level to the consensus::Configuration struct.
