- Implemented grpc based coordinator. Supports restarting, killing single or all shards, as well as getting current shard statuses. (Adaptation of the one used by the public bot)
- Coord is setup via coord.yml file
- Methods from SelfService which deal with shard/bot restart etc have been moved to ICoordinator (with GrpcRemoteCoordinator being the default implementation atm)
- Vastly simplified NadekoBot/Program.cs
