* azure: lower log priority for skipped nic update message ([#34730](https://github.com/kubernetes/kubernetes/pull/34730), [@colemickens](https://github.com/colemickens))

Rescheduler 0.3 shipped together with Kubernetes 1.6 understands the new taints and will clean up the old annotations, but Rescheduler 0.2 shipped together with Kubernetes 1.5 doesn't understand the new taints. In order to avoid eviction loop during 1.5->1.6 upgrade you need to either upgrade the master node atomically (for example...
