[LOG015] should suggest the use of logging.getLogger(__name__)

[MichaReiser]

The recently implemented LOG015 in #14302 is in conflict with LOG002. One suggests using logging.getLogger(__file__), the other calls that a bad practice. LOG015 should suggest logging.getLogger(__name__).

It also seems to be triggering when logging.getLogger(__name__) is already being used, ie, not a root logger.

LOG015 incorrectly suggests the usage of logging.getLogger(__file__) over ``logging.getLogger(name)`.
