When I do a `minikube start` I get:

```
Starting local Kubernetes v1.9.4 cluster...
Starting VM...
Getting VM IP address...
Moving files into cluster...
Setting up certs...
Connecting to cluster...
Setting up kubeconfig...
Starting cluster components...
Kubectl is now configured to use the cluster.
Loading cached images from config file.

```

However, if I do this again I get the same output.

Is this creating a new cluster, reprovisioning the existing cluster or just doing nothing?
