Version Command Panics about kubeaudit

[shane-lawrence]

If kubeaudit is run without the -l switch,

kubeaudit/cmd/kubernetes.go

Line 18 in 0995e3c

if kubeconfig == "" && !rootConfig.localMode {

assumes it's running in a cluster. If it's not, it won't have KUBERNETES_SERVICE_ environment variables set, so it returns nil and an error. The error is displayed but it doesn't abort, and

kubeaudit/cmd/kubernetes.go

Line 40 in 0995e3c

kube, err := kubernetes.NewForConfig(config)

passes a nil pointer.

@shane-lawrence one solution could be that by default set the value of local to be true and use special flag to indicate its inside a cluster.

On a side note I think we need to change that version string too.

[shane-lawrence]

The version string needs to be updated and I noticed a few times that the kubectl client version was blank so I'll look into that as well.

Here's my proposed fix for the panic: #113

Resolved by #113.
