Crypto provider for Rustls

[howardjohn]

Recently, Rustls was updated to have allow a pluggable crypto provider: https://github.com/rustls/rustls/pull/1405/files.

I believe it would now be possible to plugin boring into this. This is appealing as we get the benefits of boringssl as well as rustls - notably, FIPS compliance.

Is there interest in providing such a provider?

I tried to hack something together over the weekend that uses boring as the crypto provider: https://github.com/janrueth/boring-rustls-provider

Yeah I think this is a good idea. @janrueth thanks for hacking that together, I'll give it a look and we can go from there
