status check - error code Ok when kubernetes cluster's can't be connected.

[tejal29]

Coming from friction log

When skaffold can't connect to cluster, the error code returned is "STATUSCHECK_SUCCESS".

My gut feeling is, when cluster can't be collected, no pods are retrieved.
https://github.com/GoogleContainerTools/skaffold/blob/master/pkg/skaffold/deploy/status_check.go#L185

hence status code ok is passed

skaffold/pkg/skaffold/deploy/resource/deployment.go

Line 276 in 6994b45

return proto.StatusCode_STATUSCHECK_SUCCESS

This should be a simple change to return the deployment error code if len (d.pods) is 0.
