go build fails: github.com/coreos/etcd/client errors

[eschwartz]

I'm running make build, with go v0.13.4.
I get the following errors:

Ok, I was able to work around this by removing the ../../.gvm/pkgsets/go1.13.4/global/pkg/mod/github.com/coreos/etcd@v3.3.10+incompatible/client/keys.generated.go file.
I see there's a note in go.mod about this as well.

Let's try to find a fix for this, though. It's not a great experience for contributors that make build fails out of the box.
