[KIALI] Kiali ingress.host accepted in the SMCP but is not configured properly in Kiali CR

The SMCP CR accepts the configuration of customized ingress.hosts for Kiali, however this is not configured on the Kiali CR and route doesn't change.

spec:
addons:
grafana:
enabled: true
install:
service:
ingress:
enabled: true
jaeger:
install:
ingress:
enabled: true
storage:
type: Memory
kiali:
enabled: true
install:
dashboard:
enableGrafana: true
enablePrometheus: true
enableTracing: true
service:
ingress:
enabled: true
hosts:

• kiali-istio-system.<my-custom-subdomain>

In the appliedValues this is configured as well:

kiali:
dashboard:
enableGrafana: true
enablePrometheus: true
enableTracing: true
viewOnlyMode: false
enabled: true
ingress:
enabled: true
hosts:

• kiali-istio-system.<my-custom-subdomain>
  install: true
  resourceName: kiali

The problem seems to be in the operator helm resources as the Kiali CR only gets ingress.enabled value:

https://github.com/maistra/istio-operator/blob/5b41497a44e22dbaba6d2813117061ae6a9caa9e/resources/helm/v2.3/istio-telemetry/kiali/templates/kiali-cr.yaml#L29

For this to be configured we would probably need to implement the ingress.override_yaml which currently is not supported, since manually changing this in the Kiali CR the operator gets an error with not enough permissions to change Openshift Route specs:

ingress:
enabled: true
override_yaml:
spec:
host: kiali-istio-system.<my-custom-subdomain>

 "message": "Route kiali: Failed to create object: b'{\"kind\":\"Status\",\"apiVersion\":\"v1\",\"metadata\":{},\"status\":\"Failure\",\"message\":\"Route.route.openshift.io \\\\\"kiali\\\\\" is invalid: [spec.host: Forbidden: you do not have permission to set the host field of the route, spec.to.name: Required value]\",\"reason\":\"Invalid\",\"details\":{\"name\":\"kiali\",\"group\":\"route.openshift.io\",\"kind\":\"Route\",\"causes\":[

{\"reason\":\"FieldValueForbidden\",\"message\":\"Forbidden: you do not have permission to set the host field of the route\",\"field\":\"spec.host\"}

,

{\"reason\":\"FieldValueRequired\",\"message\":\"Required value\",\"field\":\"spec.to.name\"}

]},\"code\":422}
n'",

It would be important to have this implemented in order to work with router sharding since we can already change grafana and prometheus routes to the desired host.
