TODO

Missing things that should probably be added;

• consul-dataplane support for running mesh gateways
• consul-dataplane health check updates (automatic; manual)
• ServerExternalAddresses in a peering; possibly rig up a DNS name for this.
• after creating a token, verify it exists on all servers before proceding (rather than sleep looping on not-founds)
• investigate strange gRPC bug that is currently papered over
• allow services to override their mesh gateway modes
• remove some of the debug prints of various things
