Before opening a feature request against this repo, consider whether the feature should/could be implemented in the other OpenTelemetry client libraries. If so, please open an issue on opentelemetry-specification first.

Request
I have successfully set up the HTTP metric/trace exporter to use SSL/TLS, but I am not seeing any connection specific information logged anywhere. With debug log level, I see the [OTLP HTTP Client] Session state: connected message, but that does not contain sufficient information.

Describe the solution you'd like
Upon establishing an HTTPS connection, the negotiated TLS version and the Cipher suite should be logged. Logging the entire handshake would also be nice to have for debugging purposes.
