scheduler and proxy similarly.

Only thing I promise is that right now hack/build-go.sh and
build/release.sh exit with 0.  That's it.  Who knows if any of this

Make Vagrant CPU usage be more sane on hyperthreaded systems.

Fixes #2359
Get Vagrant to start using TLS client certs.

Also fix up cert generation. It was failing during the first salt highstate when trying to chown the certs as the apiserver user didn't exist yet.  Fix this by creating a 'kube-cert' group and chgrping the files to that.  Then make the apiserver a member of that group.

Fixes #2365
Fixes #2368
Add missing Kubernetes proxy daemon to AWS CloudFormation template.
Add external services v2 support.
