Building against kubernetes v1.5.3 client version is broken

[jescarri]

gofmt -w=true -s $(find . -type f -name '*.go' -not -path "./vendor/*")
goimports -w=true -d $(find . -type f -name '*.go' -not -path "./vendor/*")
go build -o build/bin/darwin/kube2iam -ldflags "-s -X ""github.com/jtblin"/kube2iam"/version.Version=$(git describe --abbrev=0 --tags) -X ""github.com/jtblin"/kube2iam"/version.GitCommit=$(git rev-parse --short HEAD) -X ""github.com/jtblin"/kube2iam"/version.BuildDate=$(date +%Y-%m-%d-%H:%M)" github.com/jtblin/kube2iam
# github.com/jtblin/kube2iam/cmd
cmd/k8s.go:20: undefined: "github.com/jtblin/kube2iam/vendor/k8s.io/kubernetes/pkg/client/unversioned".Client
make: *** [build] Error 2```

After running 
```glide get github.com/aws/aws-sdk-go/blob/master/aws/ec2metadata#^v1.0.8```

doing a diff to glide.lock I found that it was never updated to v1.5.3

Client version has been downgraded to 1.4.6 as part of 0.5.0

The kubernetes client code has moved to https://github.com/kubernetes/client-go/ so I updated the code to use it instead of the main kubernetes project directly as before: 68ab0a8
