Note that by just running `make update-go-deps`, the K8s Go client was
set to `k8s.io/client-go v11.0.0+incompatible`. However, that doesn't
play well with `k8s.io/apimachinery v0.18.5`. I the manually changed
the Go client line to `k8s.io/client-go v0.18.5`, which made
everything work. I guess Go Modules got confused by the ginormous
v11.0.0 version tag. Or it is a problem that pulling k8s.io/client-go
with git results in a rather old repo without the v0.18.5
tag. github.com/kubernetes/client-go has all the right tags. I
actually don't understand how Go Modules still correctly figures out
the source from the `k8s.io/client-go v0.18.5` line.
If one of the reviewers could enlighten me, I'd much appreciate it.
