Investigate Enabling HorizontalPodAutoscaler Resource in kiali chart

The Kiali chart comes with a HorizontalPodAutoscaler resource and we've confirmed that Kiali does not need any extra configuration or values present to support multiple replcas: https://repo1.dso.mil/platform-one/big-bang/bigbang/-/blob/master/docs/understanding-bigbang/package-architecture/kiali.md#high-availability

Test deploying Kiali with this HorizontalPodAutoscaler value set via hpa.spec & it's hpa.api_version and see if any of the hpa.spec values need to be tuned or altered for better performance.

If no issues or other dependencies are required, enable this HorizontalPodAutoscaler for the package in BigBang so it is enabled by default.

• Deploy and test Kiali with HorizontalPodAutoscaler resource
• Document any caveats or recommendations in above linked package-architecture/kiali.md#high-availability document
• Enable HPA in BigBang if no large caveats or recommendations are required
