Use extension trait to simplify config

Seems like a big improvement!

Another idea: we could potentially add another trait implemented directly for ClientConfig, such that you could do ClientConfig::with_platform_verifier() and ClientConfig::with_platform_verifier_and_provider(provider).

Worth doing over the current approach of rustls_platform_verifier::tls_config()?

Nice!

Your proposal seems a bit tidier to me. I'd be 👍

If we don't remove tls_config, maybe we should reimplement it in terms of the new extension trait internally for better coverage? Otherwise I think this looks fine.

Implemented a "maximalist" approach with two new traits, that deprecates the old tls_config*() API.

Updated the README and also used the new ConfigBuilder::crypto_provider() API to make sure we use the matching crypto provider.
