Doesn't handle multipule kube-config files

[switchboardOp]

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]:
github.com/emirozer/kubectl-doctor/pkg/client.tryGetKubeConfigFromEnvVar(0x50, 0xc0002c4e60, 0x1ebccc0)

doctor should respect the merged config and the current context.
