watcher is a simple service to trigger a handler when WATCHER_WATCHED_FILE is updated.
In openpitrix, the global config is load into ConfigMap when depolied by helm or kubernetes; watcher watches mounted volume dirs from ConfigMap and notifies the target process(UpdateOpenPitrixEtcd) that the config map has been changed. It currently only supports handler UpdateOpenPitrixEtcd.
