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.

Godoc improvements
Step #1 in migrating the service controller away from the apiserver.
Start using the API server for listing services.
Split api into api, api/common, api/validation & apitools
Split helper test, move fuzzing to api package as serialization_test.go
Make validation work when not in the api package.
Propagate rename; tests pass again.
Combine pkg/apitools and pkg/api/common and call the result pkg/runtime
Disable running travis at tip, it's finding a bunch of races that don't seem to be our fault
