Switch from deprecated workload APIs due to it's removal in v1.16

[lilic]

Currently, kube-state-metrics uses the deprecated extensions/v1beta1 workload APIs, but in v1.16 onwards these API are removed, so we should switch to the newer versions instead. This effects ingress and replicaset.

PR that removes it -> kubernetes/kubernetes#70672

[lilic]

Happy to make the needed changes. :)

[brancz]

Go ahead :)

@brancz Probably #796 release should happen before the above change?

[brancz]

How long as the networking API for the ingress replacement existed? If at least since kube 1.11 then I'm ok with having it in kube-state-metrics 1.7.

This API is available only from 1.14: kubernetes/kubernetes#74057

[brancz]

Ok so the ingress one we'll need to keep until 1.18 then, but replicasets we can move now.

@lilic I see that ingresses weren't included in this PR kubernetes/kubernetes#70672 and aren't slated to be removed.

So you are definitely right that it can be closed. Thanks for bringing it up.

@tariq1890 We can open a follow-up issue for switching from the deprecated ingress workloads API, so we remember to do that before the v1.18 release. If you think that will be of any help?
