This adds these new settings: records.yaml: proxy.config.ssl.server.version.min proxy.config.ssl.server.version.max proxy.config.ssl.client.version.min proxy.config.ssl.client.version.max sni.yaml: valid_tls_version_min_in valid_tls_version_max_in and deprecates these settings: records.yaml: proxy.config.ssl.TLSv1 proxy.config.ssl.TLSv1_1 proxy.config.ssl.TLSv1_2 proxy.config.ssl.TLSv1_3 proxy.config.ssl.client.TLSv1 proxy.config.ssl.client.TLSv1_1 proxy.config.ssl.client.TLSv1_2 proxy.config.ssl.client.TLSv1_3 sni.yaml: valid_tls_versions_in

Why not } else if (!unset) { ?

I guess I wanted to make it clear that if (!unset) { is the first line for the case min/max isn't used. It enables us to add some code before the if easily.

I found an incompatibility between OpenSSL and BoringSSL.
If
valid_tls_versions_inhas[TLSv1, TLSv1_2, TLSv1_3](note thatTLSv1_1isn't in the list), BoringSSL only allows TLSv1 where OpenSSL allows all the three versions. It sounds like a bug but it's actually not.https://boringssl.googlesource.com/boringssl/+/86ada1ea2f51ff41baa2919337e5d721bd27f764/ssl/ssl_versions.cc#225
And I also found that the way (API) we currently use to specify available TLS versions is deprecated.
The old way allow us to specify versions individually (like above), but the new way only allows us to specify a range of versions.
Old:
https://www.openssl.org/docs/man3.1/man3/SSL_CTX_set_options.html
https://commondatastorage.googleapis.com/chromium-boringssl-docs/ssl.h.html#SSL_OP_NO_TLSv1
New:
https://www.openssl.org/docs/man3.1/man3/SSL_CTX_set_min_proto_version.html
https://commondatastorage.googleapis.com/chromium-boringssl-docs/ssl.h.html#SSL_set_min_proto_version
Since the old way is no longer supported by SSL libraries, we should deprecate the current way and only allow ATS users to specify a range.
This adds these new settings:
