* as pointed out in #281 the currently used image for the
kube-rbac-proxy - gcr.io/kubebuilder/kube-rbac-proxy:v0.4.1" - does not
have an ARM64 image
* hence, trying to use the standard deployment manifest / helm char will
fail on ARM64 systems
* replaced image with quay.io/brancz/kube-rbac-proxy:v0.8.0 which is the
latest version from the upstream maintainer
(https://github.com/brancz/kube-rbac-proxy/blob/master/Makefile#L13)
* successfully tested on both AMD64 and ARM64 clusters
* fixes#281
