To write config items to a particular config file, we should know where is each config section and item from. Current setting functionality of perf-config use autogenerating way by overwriting collected config items to a config file. For example, when collecting config items from user and system config files (i.e. ~/.perfconfig and $(sysconf)/perfconfig), perf_config_set can contain both user and system config items. So we should know where each value is from to avoid merging user and system config items on user config file.
