Fixes #2812
I tested it only with the newest versions of locust and its dependencies.
Currently, I don't know use cases of
os.getenv("LOCUST_SKIP_URLLIB3_PATCH", None).However, this PR touches implementation details of urllib3 and gevent, so I want to provide possibility to opt-out.
(For example, it may fail with future release of urllib3.)
PR is based on this answer.
