We can self-report our ValidatorAddress in the NodeInfo for the sake of debugging while we're in testnet mode. Otherwise it's hard to figure out which validator address is associated with which peer.

Note this is not actually authenticated at any point so we shouldn't really leave it in, though it will be useful in the short term to show up in DumpConsensusState (should be added to the rpc/core/types/responses.go#PeerRoundState)
