Add a Makefile

This is a very simple Makefile that just passes through to the current hack/*
scripts.  Only "make", "make test", and "make clean" are supported for now.

Add a Makefile
Suppress non-error output of `systemctl enable`

The `systemctl enable` command ordinarily prints the `ln` command used
to enable the unit to stderr, but that's not ideal in the vagrant setup
because it gets printed in red, which should be reserved for errors, but
it's not a real error.

Set an environment variable to raise the log level to prevent `info`
messages from being printed to stderr (as they are not actually errors.)

I looked into the `systemctl` calls happening from the Salt setup script
to understand why they were not going to stderr, and it turns out the
Salt script will redirect all messages to stdout so they will all be
green regardless...

Tested:
- Started a fresh Vagrant cluster, confirmed no red messages in output
  when creating the cluster successfully. Successfully started nginx
  through Kubernetes using cluster/kubecfg.sh.
- Confirmed that the salt-api service was up after `vagrant up`:
  $ vagrant ssh master -c 'systemctl status salt-api.service'
  salt-api.service - The Salt API
     Loaded: loaded (/usr/lib/systemd/system/salt-api.service; enabled)

Add support for -version=raw to print the Go version.Info

This can be helpful to print the internal fields of the version
information that will contain more details about the git tree than the
short -version output will.

Tested:
- Tested getting the raw version:
  $ _output/go/bin/kubecfg -version=raw
  version.Info{Major:"0", Minor:"1+", GitVersion:"v2.2.1-33-gdc4becd9765393", GitCommit:"dc4becd9765393fa05a3eb06f6af9e00068fe0c5", GitTreeState:"dirty"}

- Tested getting the simple version:
  $ _output/go/bin/kubecfg -version
  Kubernetes version 0.1+, build dc4becd9765393fa05a3eb06f6af9e00068fe0c5

- Tested getting the help output:
  $ _output/go/bin/kubecfg 2>&1 | grep -- -version
    -version=false: Print version information and quit

- Made sure -version=true and -version=false works, that -version with
  an invalid argument works as expected (prints usage help) and that
  -version followed by space will not try to use the next word as its
  argument (i.e. `-version raw` prints the version but not the raw one.)

Rename `pkg/version/flag` to `pkg/version/verflag`

This avoids some conflict with the built-in `flag` module in Go. The
module was already being renamed to `verflag` on import anyways, so we
might as well just call it that.

Tested:
- hack/build-go.sh and ran the resulting binaries with -version args.
