[issue39540] Logging docs don't address the creation of multiple loggers when a hierarchy is provided

[Alexander McFarlane]

New submission from Alexander McFarlane <alexander.mcfarlane at nomura.com>:

If `logger_name` is a hierarchy format (e.g. `logger_name = 'parent.child'`) and the logger name `'parent'` has not been created, the function call `logging.getLogger(logger_name)` will create all loggers in the hierarchy (in this instance two loggers, `'parent'` and `'parent.child'` will be created)

This is not documented anywhere in the logging documentation. Suggest that this is detailed under `logging.getLogger`
