In OSSM-214 it was requested to stop using in Kiali a deprecated OpenShift API. 

Kiali is moving away from the deprecated API, but some values are passed by the maistra-operator. These values seem to be hardcoded in maistra-operator, or that's what a simple GitHub Query shows:

https://github.com/maistra/istio-operator/search?q=%2Fvar%2Frun%2Fsecrets&unscoped_q=%2Fvar%2Frun%2Fsecrets

Kiali-operator will be using, by default, the cabundle from OpenShift for jaeger, prometheus and grafana. So, it's no longer needed that maistra-operator writes the ca_file attributes in the Kiali CR.

This change is needed for SM1.0 and 1.1, plus the current dev version.
