> In KAFKA-7251 support of TLS1.3 was introduced.
> For now, only TLS1.2 and TLS1.3 are recommended for the usage, other versions 
> of TLS considered as obsolete:
> https://www.rfc-editor.org/info/rfc8446
> https://en.wikipedia.org/wiki/Transport_Layer_Security#History_and_development
> But testing of TLS1.3 incomplete, for now.
> We should enable actual versions of the TLS protocol by default to provide to 
> the users only secure implementations.
> Users can enable obsolete versions of the TLS with the configuration if they 
> want to.
