ONLY APPLIES TO 3.0

The Kiali CR has several settings being renamed (see https://github.com/kiali/kiali/issues/7745 ).

Basically, the grafana and tracing settings called "url" and "in_cluster_url" will be renamed to "external_url" and "internal_url" respectively

To be specific, the old names --> new names are:

• external_services.grafana.url --> external_services.grafana.external_url
• external_services.grafana.in_cluster_url --> external_services.grafana.internal_url
• external_services.tracing.url --> external_services.grafana.external_url
• external_services.tracing.in_cluster_url --> external_services.grafana.internal_url

We need to change downstream docs to reflect the new names. For example, this page would need to be updated: https://docs.openshift.com/container-platform/4.14/service_mesh/v2x/ossm-observability.html

The old names are deprecated, but will still take precedence if used (thus things are backward compatible).
