[RFC PATCH 1/2] list_objects_filter_options: introduce 'list_object_filter_config_name'
In a subsequent commit, we will add configuration options that are
specific to each kind of object filter, in which case it is handy to
have a function that translates between 'enum
list_objects_filter_choice' and an appropriate configuration-friendly
string.
