Prior to this fix, openapi spec for prometheus-adapter apiextension was based on the type "k8s.io/sample-apiserver/pkg/apiserver" which is incorrect. Due to the incorrect type, `kubectl explain podmetrics` (or nodemetrics) wasn't showing any doc for any resources from metrics.k8s.io/v1beta1.
This changeset fixes the problem by using the right type(sigs.k8s.io/metrics-server/pkg/api) for the openapi generation.
This also helped to remove the sample-apiserver dependency from
prometheus-adapter.

Include a fix to the NodeMetrics and PodMetrics APIs to match k8s
conventions.
- NodeMetrics and PodMetrics now have labels as they can be filtered by
them
- Field selector is now applied to NodeMetrics and PodMetrics instead
of Nodes and Pods

Pick up changes to 1.17 to custom-metrics-apiserver and the latest
changes in metrics-server to allow us to show table results for
podmetrics and nodemetrics. Fix import and interface changes as
necessary.
The localvendor directory is an artifact of a change in sigs.k8s.io:
sigs.k8s.io/metrics-server now requires this dependency in order to
resolve, even though we do not use the scraper package.
go: sigs.k8s.io/metrics-server@v0.3.7 requires
