Consider Adding Timeout in cache.WaitForCacheSync

[sargun]

This can last forever:

virtual-kubelet/vkubelet/podcontroller.go

Lines 123 to 125 in 1942522

	if ok := cache.WaitForCacheSync(ctx.Done(), pc.podsInformer.Informer().HasSynced); !ok {
	return pkgerrors.New("failed to wait for caches to sync")
	}

The node will show up, and continue to heartbeat, but never get back into sync. I suggest two things:

1. That the node doesn't show up as up until this completes
2. We add a timeout here that's reasonable, or configurable.

Fixed!

Hi. I'm facing this issue too. What was the solution at the end? I tried using --startup-timeout option, but the startup just exits once the timeout has reached.
