def collect_plugins_in_apps(module_name: str, module_attr: str) -> Dict[str, Any]:
    Searches for [module_name].py in each app. If there is such module and it has
    [module_attr] attribute in it then add it to the resulting dictionary with key = application name.

    This way we can provide a pluggable architecture for various subsystems.
    For example:
        Documents app searches for "python_coded_fields.py" in each available app.
        It takes PYTHON_CODED_FIELDS list from each found module and puts fields from it in the
        big field registry.
