[Enhancement] HTTP2 support

[mycodeself]

Description

Hello 👋🏼

I'm testing the operator and I think it does not support HTTP2 because it uses python requests.

Would you consider changing the HTTP client to httpx or any other to include http2 support?

If you agree, I would be willing to contribute...

thanks!

I'm curious why you need http2.

But I'm fine with changing it, so go ahead.

hey @rndmh3ro thanks for your answer.

The problem I'm facing is basically that we enforce by default HTTP2 in our internal ALB+nginx controller, and when testing the operator we were having errors 464 from the AWS ALB, and looks like the issue is because the requests of the operator are sent using HTTP1.
