--quiet suppression of progress bar not honored when specifying custom log location with --log /path/to/log.log

Description

when executing pip using both --quiet and --log, the progress bar is shown.

primarily using python 3.8 with pip version 21.1.1 on linux, however tested to see the same behavior with python 3.10 & pip 21.3.1 on windows. commands executed:

linux (python 3.8, pip 21.1.1): python3.8 -m pip install --quiet --no-cache-dir --no-deps --log ./test.log --target ./test numpy
windows (python 3.10, pip 21.3.1): python -m pip install --quiet --no-cache-dir --no-deps --log ./test.log --target ./test numpy

in this case, we're automatically creating necessary archives for lambda layers so we don't want any additional noise except errors, etc, which we're already capturing.

Expected behavior

expected behavior: completely silent output including no progress bar.

pip version

21.1.1

Python version

3.8

OS

linux

How to Reproduce

run python -m pip install --quiet --no-cache-dir --no-deps --log ./test.log --target ./test numpy to see progress bar

run python -m pip install --quiet --no-cache-dir --no-deps --target ./test numpy to see silent operation

Output

python3.8 -m pip install --quiet --no-cache-dir --no-deps --log ./test.log --target ./test numpy
