Gevent + Urllib3 Recursion Bug (Regression)

[TimPansino]

Description

After the upgrade to urllib3 in version 7.2.0, a regression for the gevent + urllib3 recursion occurred.

Expected Behavior

Gevent patching after agent initialization should not cause a crash in the agent.

Steps to Reproduce

import newrelic.agent
newrelic.agent.initialize()

from gevent import monkey
monkey.patch_all()

import requests
r = requests.get('https://www.google.com/')
print(r)

Your Environment

gevent==21.8.0
newrelic==7.2.1.168
requests==2.26.0
urllib3==1.26.7

Additional Context

Relevant comment from codebase with links:

# This is a monkey patch for urllib3 + python3.6 + gevent/eventlet.
# Gevent/Eventlet patches the ssl library resulting in a re-binding that causes
# infinite recursion in a super call. In order to prevent this error, the
# SSLContext object should be accessed through the ssl library attribute.
