This ensures that the daemonset controller updates daemonset statuses in a best-effort manner even if syncDaemonSet fails. In order to add an integration test, this also replaces `cmd/kube-apiserver/app/testing.StartTestServer` with `test/integration/framework.StartTestServer` and adds `setupWithServerSetup` to configure the admission control of the apiserver.
