Subject: [PATCH] Add arch node selector for hybrid clusters

Currently, all of the lens-metrics components are multi-arch except for kube-state-metrics.  On a hybrid cluster this can be scheduled for arm, arm64 or other nodes so the pod will never come up.

- kube-state-metrics image only supports amd64 - https://github.com/kubernetes/kube-state-metrics/issues/1037.  There is a PR for this, but it hasn't been merged yet and seems to be held up.  Alternatively we could switch to use a different image: https://hub.docker.com/r/carlosedp/kube-state-metrics/tags but just limiting the state metrics to amd64 is the easier option
