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.
fluend-gcp already has these tolerations. kube-proxy when it runs as a
static pod gets wildcard `NoExecute` toleration (all static pods get
that). So, added the same toleration to kube-proxy when it runs as a
daemonset. Also added wildcard `NoSchedule` toleration to kube-proxy.

Move fluentd-gcp out of host network
Since metadata proxy doesn't filter service account after all, make fluentd-gcp addon run in its own network
This will mitigate the problem with port collision
```release-note
[fluentd-gcp addon] Fluentd now runs in its own network, not in the host one.
```
- Use a dedicated service account to run the fluentd-gcp DS
- Update prometheus-to-sd from v0.1.3 to v0.2.1
- Use the certificates in the prometheus-to-sd image rather than mounting the host certs

Add event exporter deployment to the fluentd-gcp addon
Introduce event exporter deployment to the fluentd-gcp addon so that by default if logging to Stackdriver is enabled, events will be available there also.
In this release, event exporter is a non-critical pod in BestEffort QoS class to avoid preempting actual workload in tightly loaded clusters. It will become critical in one of the future releases.
```release-note
Stackdriver cluster logging now deploys a new component to export Kubernetes events.

Cleanup fluentd-gcp image, rebase on debian-base
**Why we need this PR**:
There are several problems with our current fluentd-gcp image:
- It pulls in lots of unused packages, which expose unnecessary risk and create noise in CVE scans (and scare customers). The most notable example is the fluent-ui, which pulls in rails.
- `curl | sh ` is not a good practice for a Dockerfile. First, the script is not checked in the same source control branch, so builds are not reproducible. Second, the actions it is taking are opaque. Third, in this case, using non-standard packages means they're harder to manage with CVE scans & upstream fixes.
**What is changed by this PR?**
- Rather than relying on td-agent (which includes fluent-ui), use standard upstream packages. This is largely based off the [official fluentd debian-based image](https://github.com/fluent/fluentd-docker-image/blob/master/v0.12/debian/Dockerfile).
- Rebases the image on debian-base (depends on https://github.com/kubernetes/kubernetes/pull/41915). We would like to move towards a single full-distro base image we can maintain. This change should be relatively minor.
As a result of these changes, the image size is reduced from 360.6 MB to 185.8 MB (nearly half). Many packages were removed, and the full diff (focus on the unversioned files) is listed here: 3fb704f977
**Which issue this PR fixes** https://github.com/kubernetes/kubernetes/issues/40248
**Special notes for your reviewer**:
This change both addresses security concerns, and is expected to greatly reduce the maintenance burden of the fluentd-gcp image. I'd *really* like to get this into 1.6, so please prioritize this review if possible.
I tested this by running the default e2e suite on a private e2e cluster using the new image. If there are other tests you'd like me to run, please let me know ASAP.
**Release note**:
```release-note
Cleanup fluentd-gcp image: rebase on debian-base, switch to upstream packages, remove fluent-ui & rails
```
