Revert "Remove rescheduler and corresponding tests from master"
Reverts kubernetes/kubernetes#64364
After discussing with @bsalamat on how DS controllers(ref: https://github.com/kubernetes/kubernetes/pull/63223#discussion_r192277527) cannot create pods if the cluster is at capacity and they have to rely on rescheduler for making some space, we thought it is better to
- Bring rescheduler back.
- Make rescheduler priority aware.
- If cluster is full and if **only** DS controller is not able to create pods, let rescheduler be run and let it evict some pods which have less priority.
- The DS controller pods will be scheduled now.
So, I am reverting this PR now. Step 2, 3 above are going to be in rescheduler.

Use default seccomp profile for flutend-elasticsearch addons
**What this PR does / why we need it**:
This PR sets the default seccomp profile to 'docker/default' for:
- fluentd-es daemon set.
- kibana-logging deployment.
The elasticsearch-logging stateful set is still unconfined because it uses gce:podsecuritypolicy:privileged.
This PR is a followup of #62662. We are using 'docker/default' instead of 'runtime/default' in addons in order to handle node version skew. When seccomp profile is applied automatically by default later, we can remove those annotations.
This is PR is part of #39845.

Remove mapping to /host/lib from fluentd-gcp container.
**What this PR does / why we need it**:
This mapping is no longer needed since fluentd-gcp v2.0.16, in which it started using a container image based on Debian Stretch, in which the systemd libraries already include support for all the supported
compression algorithms.
The `/run.sh` in the image no longer accesses `/host/lib` anyways, so let's stop mapping it here.

Due to updates in Fluent v0.14, the buffers directory modified date is no
longer updated when files inside the directory are changed. Therefore we

Bump to etcd 3.1.12 to pick up critical fix
etcd [3.1.12](https://github.com/coreos/etcd/releases/tag/v3.1.12) (as well as 3.2.17 and 3.3.2) was released yesterday to fix a bug critical to kubernetes:
Fix [mvcc "unsynced" watcher restore operation](https://github.com/coreos/etcd/pull/9297).
- "unsynced" watcher is watcher that needs to be in sync with events that have happened.
- That is, "unsynced" watcher is the slow watcher that was requested on old revision.
- "unsynced" watcher restore operation was not correctly populating its underlying watcher group.
- Which possibly causes [missing events from "unsynced" watchers](https://github.com/coreos/etcd/issues/9086).
This will be backported to 1.9 as well.
Release note:
```release-note
Upgrade the default etcd server version to 3.1.12 to pick up critical etcd "mvcc "unsynced" watcher restore operation" fix.
```

Rollback etcd server version to 3.1.11 due to #60589
Ref https://github.com/kubernetes/kubernetes/issues/60589#issuecomment-371171837
The dependencies were a bit complex (so many things relying on it) + the version was updated to 3.2.16 on top of the original bump.
So I had to mostly make manual reverting changes on a case-by-case basis - so likely to have errors :)

```release-note
Downgrade default etcd server version to 3.1.11 due to #60589
