// First global configuration is loaded then local one if it exists.
// Notes on global/local configuration:
// 1. All global config data is inherited unless some carrier properties
// are overidden or carrier deals are explicitly marked as excluded.
// 2. Local config could mark that all carrier deals should be excluded or
// only specific carrier deals are excluded.
// 3. New ID mappings in local config are not supported.
// 4. If local config exists, at least trivial global config should exist too.
// 5. If any error occurs while parsing global/local config,
// MobileConfig::IsReady() will return false.
