Use {{ .Release.Namespace }} in ClusterRoleBinding subject namespace

[etutuit]

Is this a bug fix or adding new feature? Bug fix

What is this PR about? / Why do we need it? PR is about making subject namespace in ClusterRoleBinding generated based on the namespace release is being deployed to.

With previous hardcoded value of kube-system the test was failing because ServiceAccount didn't have proper permissions assigned, if it was deployed to different namespace than kube-system.

What testing is done? It was deployed into test cluster and ended up with successful execution after deploying to custom namespace.

Hi @etutuit. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available [here](https://git.k8s.io/community/contributors/guide/pull-requests.md). If you have questions or suggestions related to my behavior, please file an issue against the [kubernetes-sigs/prow](https://github.com/kubernetes-sigs/prow/issues/new?title=Prow%20issue:) repository.
