Elisiano Petrini b1bab7de39 Added metrics-server deployment for 1.16+ 
Since kubernetes 1.16 does not support older deployments api versions
this needs to be updated as well.

Added addon.yaml and amended README.md

Replace gcr.io URL with k8s.gcr.io vanity URL 
This is just the changes that aren't for backwards compatability, from
the bigger #4931

Set metrics server to use insecure tls 
In 0.3.x, the secure kubelet port with auth is enabled by default. Use
of the insecure port is deprecated and may even be removed as soon as
the next release. See:
* https://github.com/kubernetes-incubator/metrics-server/releases/tag/v0.3.0
* https://github.com/kubernetes-incubator/metrics-server/releases/tag/v0.3.1

That said, metrics-server now uses webhook authentication so kubelet
would need webhook authentication enabled (which we don’t). This flag
enables, that serviceaccount tokens to be used to authenticate against
the kubelet: See:
* https://kubernetes.io/docs/reference/access-authn-authz/webhook/
* https://github.com/kubernetes/kops/pull/5508
* https://github.com/kubernetes/kops/issues/5176#issuecomment-402454053
* https://github.com/kubernetes-incubator/metrics-server/issues/175

Currently, even if we were to use certificates, this provides a
challenge since metrics server will generate it’s own self-signed
certificates since we don’t set `--tls-cert-file` and
`--tls-private-key-file`. Related:

Set metrics-server preferred address types 
So, v0.3.0 changed how the options are specified, so it makes sense that
we needed to make this change. See:
* https://github.com/kubernetes/kubernetes/issues/44540#issuecomment-424508625
* https://github.com/kubernetes/kubernetes/issues/44540#issuecomment-425218584

From checking the address preferences configured on our API server i.e.
and then mirroring those options to metrics-server. See:
* https://github.com/kubernetes-incubator/metrics-server/issues/67#issuecomment-438421549
