* Cleanup fluentd-gcp image: rebase on debian-base, switch to upstream packages, remove fluent-ui & rails ([#41998](https://github.com/kubernetes/kubernetes/pull/41998), [@timstclair](https://github.com/timstclair))

  -  Fixed a bug that could cause CoreDNS to stop updating service records.
  -  Fixed a bug in the forward plugin where only the first upstream server is always selected no matter which policy is set.
  -  Remove already deprecated options `resyncperiod` and `upstream` in the Kubernetes plugin.

- File descriptors are leaked in docker v1.11 ([#275](https://github.com/docker/containerd/issues/275))
- Additional memory overhead per container in docker v1.11 ([#21737](https://github.com/docker/docker/issues/21737))
- [List of upstream fixes](https://github.com/docker/docker/compare/v1.10.3...runcom:docker-1.10.3-stable) for docker v1.10 identified by RedHat
