[issue18046] Simplify and clarify logging internals

[Alex Gaynor]

New submission from Alex Gaynor:

This patch splits a dictionary that maps integer and string representations of levels to each other out into two dictionaries, one which goes int -> string, and the other which is string -> int. This makes it easier to reason about what a variable contains.
