dbarbosa 2649b4bf74 Add label platform/application to pods
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.
