urllib3 was recently bumped to 2.x[1] in global upper constraints.
Adopt the unit tests to fix a few new errors.
The key points are
- It now strictly requires byte response
- It ignores CN to verify SSL certificates and we should add SAN
Also leave the script to generate test certificates and keys so that
we can adjust these in the future more easily.
