    config_file: do not refresh read-only backends
    
    If calling `config_refresh` on a read-only configuration file backend,
    then we will segfault when comparing the timestamp of the file due to
    `path` being uninitialized. As a read-only snapshot should not be
    refreshed anyway and stay consistent, we can simply return early when
    calling `config_refresh` on a read-only snapshot.
