Defer logging.handlers with a plain lazy import in config.py

Drops the "as logging_handlers" alias and the nine renames that came with
it. The dotted spelling defers the submodule just as well for import time,
and resolving the module's own logging global is what binds handlers in
vars(logging) again, so the documented handlers.X spelling in fileConfig()
config files works in a fresh process.
