We can then avoid the following warning:
```
WARNING: The '--' argument must be specified between gcloud specific args on the left and DOCKER_ARGS on the right. IMPORTANT: previously, commands allowed the omission of the --, and unparsed arguments were treated as implementation args. This usage is being deprecated and will be removed in March 2017.
This will be strictly enforced in March 2017. Use 'gcloud beta docker' to see new behavior.

1. Use --client since -c is deprecated now
2. The command (./kubectl version --client | grep -o 'GitVersion:"[^"]*"')
now returns:
GitVersion:"v1.4.0-alpha.1.784+ed3a29bd6aeb98-dirty"
so parse out the version better using sed

This allows us to start building real dependencies into Makefile.
Leave old hack/* scripts in place but advise to use 'make'. There are a few
rules that call things like 'go run' or 'build/*' that I left as-is for now.
