Add support to 'app.starlingx.io/component' to be overwritten by user override, with possible values being 'platform' and 'application'. With 'platform' being the default value. This change will also restart the pods if the label changes. Test Plan: PASS: build-pkgs -c -p metrics-server-helm/stx-metrics-server-helm PASS: upload/apply/remove/delete/update metrics-server. PASS: Install metrics-server and check if pods have the label 'app.starlingx.io/component' with the value 'platform'. PASS: Change the value of the isApplicationLabel to true using "system helm-override-update" and check, if after re-applying the app, the label 'app.starlingx.component' changes to application' in the pods. PASS: Use 'system application-apply metrics-server' when there is a change to be applied to 'app.starlingx.component' and verify if the pod is restarted. PASS: If "isApplicationLabel" is updated with a value other than true or false, the label on the pods "app.starlingx.io/component" will not change.
