Add flag to the kafka topics command to ignore invalid/self signed certs

Just investigate if that is possible.

I investigated if this is possible and yes, it is.

A TLS flag can be passed here to allow insecure connections:

dialer := &kafka.Dialer{
	Timeout:   100 * time.Second,
	DualStack: true,
	// #nosec 402
	TLS: &tls.Config{
		InsecureSkipVerify: insecure,
	},
}

Adding rhoas kafka topic sticky unsecure flag would be amazing and allow us to work with production backend

Yes, and I tried using Cobra persistent flags to achieve this but they did not behave as I expected them to.
