Rename the Helm repository to avoid using the same name used by other
applications in the kube-system namespace.
This fixes a bug where HelmRepository objects belonging to multiple
apps were being removed from the cluster when running "system
application-remove".
Test Plan:
PASS: build-pkgs && build-image
PASS: AIO-SX fresh install
PASS: upload/apply/update/remove/delete app
