Create system:cluster-autoscaler account & role and introduce it to C…
**What this PR does / why we need it**:
This PR adds cluster-autoscaler ClusterRole & binding, to be used by the Cluster Autoscaler (kubernetes/autoscaler repository).
It also updates GCE scripts to make CA use the cluster-autoscaler user account.
User account instead of Service account is chosen to be more in line with kube-scheduler.
**Which issue(s) this PR fixes**:
Fixes [issue 383](https://github.com/kubernetes/autoscaler/issues/383) from kubernetes/autoscaler.
**Special notes for your reviewer**:
This PR might be treated as a security fix since prior to it CA on GCE was using system:cluster-admin account, assumed due to default handling of unsecured & unauthenticated traffic over plain HTTP.
**Release note**:
```release-note
A cluster-autoscaler ClusterRole is added to cover only the functionality required by Cluster Autoscaler and avoid abusing system:cluster-admin role.
action required: Cloud providers other than GCE might want to update their deployments or sample yaml files to reuse the role created via add-on.

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.
/cc @bsalamat @aveshagarwal @k82cn
Please let me know your thoughts on this.
```release-note

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.
