Create `config` package nearby storage node application. Implement `Config` as a wrapper over `viper.Viper` that provides the minimum functionality required by the application. The constructor allows you to read the config from the file. Methods are provided for reading subsections and values from the config tree. Helper functions are implemented to cast a value to native Go types. Signed-off-by: Leonard Lyubich <leonard@nspcc.ru>
