Introduce qualified name instead of function name in logging

[NN---]

Feature or enhancement

Proposal:

class A:
  def f():
    logger = logging.getLogger("a")
    logger.use_qualname = True

    formatter = logging.Formatter("%(funcName)s - %(message)s")
        
    handler.setFormatter(formatter)
    logger.addHandler(handler)
    logger.setLevel(logging.INFO)

    logger.info("abc")

Result will include classname and not just function.

Has this already been discussed elsewhere?
