A "global" log level set by log_level cannot be overridden at the test level.

Minimal Example:

# setup.cfg
[tool:pytest]
log_level = CRITICAL

# test_example.py
import logging


def function_that_logs():
    logging.debug('message')


def test_logger(caplog):
    caplog.set_level(logging.DEBUG)
    function_that_logs()
    assert caplog.text

Running pytest-master@077d1c3, Python 3.7.6.

It looks like this is because log_level adjusts the level of LogCaptureHandler() in _runtest_for_main() whereas caplog.set_level() adjusts the level of a specific Logger (likely Root).

If I add self.handler.setLevel(level) to the end of LogCaptureFixture.set_level() the above example passes. Is this a suitable fix (assuming the corresponding cleanup is added too)? Or is this a misuse of log_level?
