Add Full Support for ServiceDiscovery

[PisanoCyberG]

This PR implements functionality for ServiceDiscovery Instances. It also adds support for the missing update_http_namespace() function.

Functions added:

• update_http_namespace()
• register_instance()
• deregister_instance()
• get_instance()
• get_instances_health_status()
• update_instance_custom_health_status()
• list_instances()
• discover_instances()
• discover_instances_revision()

This leaves ServiceDiscovery at 100% implementation.

Feedback on any issues is welcome!

Thank you for taking a look at my changes! Those whitespace changes are changing CRLF to just LF. Previously different files had different methods of encoding line breaks. I've changed them to all follow the Linux standard of LF, since CRLF broke some files (in particular the shebangs at the tops of python files). Let me know if you would still like me to revert and I will be happy to do so.

I have reverted the whitespace changes. Let me know if I can do anything else for you!

I've noticed some issues with dict and list typing issues in Python 3.8. I have fixed this in the latest commit.

Looks like there are a few errors during the 3.12 tests, although they seem to be relating to other services (Lambda, CloudWatch, etc.). Could that be an issue with my proposed changes?

I think Github had some hickups last night - all Docker tests failed randomly, on all PR's. Restarting the build fixed it.
