Setting a basicConfig before importing distributed changes the scheduler logging level.

[Thomas-Z]

Hello,

Some kind of follow-up to the #7527 issue.

Describe the issue:

Setting a basicConfig before the distributed import changes the logging level of the scheduler to INFO.
Doing the same with the distributed import before the logging configuration does work as intended.

Minimal Complete Verifiable Example:

import logging

DEFAULT_FORMAT = "%(asctime)s %(levelname)-7s %(message)s"
DEFAULT_TIME_FORMAT = "%Y-%m-%d %H:%M:%S"

logging.basicConfig(format=DEFAULT_FORMAT, datefmt=DEFAULT_TIME_FORMAT)


import distributed

loc_cluster = distributed.LocalCluster(
    processes=False, n_workers=1, silence_logs="ERROR"
)

This code output the following logs:
