Description

Currently TLS minimum version i hardcoded to TLS 1.2
Max version not specified currently.

No way to restrict to specific version.

Ask is to allow to restrict via config, for example something like:

    tls:
       internode:
          server:
             minVersion: "1.3"
             maxVersion: "1.3"
       frontend:
            server:
               minVersion: "1.3"
               maxVersion: "1.3"

One last thing could be to look at comment in tls_config_helper.go where it says

  // Helper methods for creating tls.Config structs to ensure MinVersion is 1.3

but code sets

  MinVersion: tls.VersionTLS12,

might be a typo in comment. Thanks!
