TODO(ihmccreery): remove once we don't care about v1.0 anymore, (tentatively in v1.3).

func BlockNetwork

func foo() {
	...

	...

Also, it ensures that at least minPods are running and ready. It has separate behavior from other 'wait for' pods functions in that it requires the list of pods on every iteration. This is useful, for example, in cluster startup, because the number of pods increases while waiting. If ignoreLabels is not empty, pods matching this selector are ignored and this function waits for minPods to enter Running/Ready and for all pods matching ignoreLabels to enter Success phase. Otherwise an error is returned even if there are minPods pods, some of which are in Running/Ready and some in Success. This is to allow the client to decide if "Success" means "Ready" or not.
