    config: skip r/o backends when writing
    
    Configuration backends have a readonly-flag which is currently used to
    distinguish configuration snapshots. But somewhat unexpectedly, we do
    not use the flag to prevent writing to a readonly backend but happily
    proceed to do so.
    
    This commit modifies logic to also honor the readonly flag for
    configuration setters. We will now traverse through all backends and
    pick the first one which is not marked as read-only whenever we want to
    write new configuration.
