refactor(config): move LevelDB option reading from Storage to StorageConfig

- Move default/defaultM/defaultL LevelDB option reading into
  StorageConfig.readDbOption(), Storage no longer touches Config directly
- Remove dead externalIp(Config) bridge method, fix test to call
  externalIp(NodeConfig) directly
- Remove setIfNeeded and Config field from Storage
