Insecure versions of SSL/TLS shouldn't be used anymore. Update the metrics stream configurations to use TLS 1.2+
Per Sonar: This rule raises an issue when an SSL/TLS is configured at application level with an insecure version (ie: a protocol different from "TLSv1.2" or "TLSv1.3").
Addressed in #564
Note: since these packages in Steeltoe 2.x target .NET Standard 2.0, TLS 1.3 is not available so the only option is TLS 1.2
