Doesn't handle multipule kube-config files #3
Description
I work with more than one cluster, so I set the KUBECONFIG environment variable to list of paths to configuration files as described here.
This causes doctor to panic.
panic: stat /Users/me/.kube/config:/Users/me/.kube/mini-kube-config:/Users/me/.kube/dev-kube-config:/Users/me/.kube/prod-kube-config: no such file or directory
goroutine 1 [running]:

doctor should respect the merged config and the current context.
