[issue9576] logging.addLevelName in file-based configurations

I set to "pending" and "wontfix" to indicate what my proposed resolution was, and to await feedback - sorry for the misunderstanding.

The custom levels feature is not intended to be used casually (as it will cause unpredictable behaviour when used differently in different third-party libraries), but there are less common application-level scenarios (where logging interoperability is less of an issue) where custom levels might be needed - which is why they are provided.

It seems acceptable to me to have different conventions for third-party code and application code. For example, NullHandler is recommended for use with third-party libraries but is not especially useful for applications.

Configuration is not intended to *completely* cover the programmatic API - just to make it easier to do the most commonly-required things.
