@zhujian7 would this PR take care of existing MSA addons created in a custom namespace ?
So if I am for example on ACM 2.7 and have an MSA addon in a test-ns ns, would this fix prevent the test-ns to be deleted when upgrading to ACM 2.9 ?

[zhujian7]

@birsanv Yes, this will prevent the test-ns from being deleted and will ignore the test-ns but use the open-cluster-management-agent-addon in 2.9
