Make `HTTPProvider.get_request_headers()` a class-level method

[antazoey]

What feature should we add?

At the time of writing this issue, the method is defined here:
https://github.com/ethereum/web3.py/blob/main/web3/providers/rpc/rpc.py#L119-L123

It is:

    def get_request_headers(self) -> Dict[str, str]:
        return {
            "Content-Type": "application/json",
            "User-Agent": construct_user_agent(str(type(self))),
        }

I am requesting this method be exposed at the class-level, to be re-written as:

    @classmethod
    def get_request_headers(cls) -> Dict[str, str]:
        return {
            "Content-Type": "application/json",
            "User-Agent": construct_user_agent(str(cls)),
        }

Use-case: This allows me to grab the default headers before constructing an HTTPProvider object for the purpose of modifying them / appending to them, without having to redefine.

Yep, we can do that!

@antazoey this was just released in web3.py v7.2.0 in case you need to reach for it.

Thanks, for reasons of my own doing, we are not able to officially update web3.py until Ape's 0.9 release
