net: don't reject domain names with only numbers and hyphens

From https://github.com/golang/go/issues/17659#issuecomment-423113606 ...

> In kubernetes , isDomainName reject Pods "A Record" "pod-ip-address",
> for example: "172-17-0-16", as RFC 3696 section 2 requires
> "top-level domain names not be all-numeric", but this example has
> three hyphen, so I think it should not be reject.
