Does not build. Will look into it.

After running go get -u ./... on this PR (as make update is broken), I get following error:

go: finding module for package github.com/googleapis/gnostic/OpenAPIv2
../../../go/pkg/mod/k8s.io/client-go@v11.0.0+incompatible/discovery/discovery_client.go:29:2: module github.com/googleapis/gnostic@latest found (v0.5.1), but does not contain package github.com/googleapis/gnostic/OpenAPIv2

It seems the dependencies were not properly updated?

Updating the dependencies causes issues
This will be addressed on Kubernetes 1.19 is out.

@ipochi should we keep the branch around?
