Current version of kiali int tests is using some hardcoded values and expects configuration which is not always matched in the mixed env.

Problems:

• hardcoded istio-system namespace, e.g. here or here
• hardcoded bookinfo namespace, e.g. here
• grafana is always expected which is not true for 3.0 - https://github.com/kiali/kiali/blob/master/tests/integration/tests/kiali_urls_test.go#L55
• TestNoIstiod is failing when having more Kiali CRs
• workloadsTest is expecting some external dashboards
• istio ingress is expected in istio-system
