Discussed in #1195

The proposed solution of #1089 is to add the custom plugin, which prints access logs. In pypa/pip#11091 windows CI has been worked 6 hours and then failed. I think, I need to disable logging at all, but there is no way to do it.

Based upon this stacktrace from my PR, looks like culprit is acceptor.join() line. Specially on Windows 10, looks like this never completes and hangs the test. https://github.com/abhinavsingh/proxy.py/runs/6903663466?check_suite_focus=true
