This is the 2nd attempt. The previous was reverted while we figured out
the regional mirrors (oops).
New plan: k8s.gcr.io is a read-only facade that auto-detects your source
region (us, eu, or asia for now) and pulls from the closest. To publish
an image, push k8s-staging.gcr.io and it will be synced to the regionals
automatically (similar to today). For now the staging is an alias to
gcr.io/google_containers (the legacy URL).
When we move off of google-owned projects (working on it), then we just
do a one-time sync, and change the google-internal config, and nobody
outside should notice.
We can, in parallel, change the auto-sync into a manual sync - send a PR
to "promote" something from staging, and a bot activates it. Nice and
visible, easy to keep track of.

Moves dns-horizontal-autoscaler to a separate service account
Similar to #38816.
As one of the cluster add-ons, dns-horizontal-autoscaler is now using the default service account in kube-system namespace, which is introduced by https://github.com/kubernetes/kubernetes/blob/master/cluster/addons/e2e-rbac-bindings/random-addon-grabbag.yaml for the ease of transition. This default service account will be removed in the future.
This PR subdivides dns-horizontal-autoscaler to a separate service account and setup the necessary permissions.

Bump up dns-horizontal-autoscaler to 1.1.1
cluster-proportional-autoscaler 1.1.1 is releasing by kubernetes-incubator/cluster-proportional-autoscaler#26, also bump it up for dns-horizontal-autoscaler to introduce below features:
- Add PreventSinglePointFailure option in linear mode.
- Use protobufs for communication with apiserver.
- Support switching control mode on-the-fly.
Note:
The new entry `"preventSinglePointFailure":true` ensures kube-dns to have at least 2 replicas when there is more than one node. Mitigate the issue mentioned in #40063.

These files have been created lately, so we don't have much information
about them anyway, so let's just:
- Remove assignees and make them approvers
- Copy approves as reviewers

Adds assignees for kube-dns
Adds assignees for auto-assigning. Does not add assignees for pkg/dns folder as we are moving it out.
