Fix exception detection in new version of fluentd-gcp addon
**What this PR does / why we need it**:
The `detect_exceptions` plugin is used to group log entries that belong to a common exception together into one log message. A [recent change](1ca851baec/cluster/addons/fluentd-gcp/fluentd-gcp-configmap.yaml (L100)) to the configuration modified which field is used for the log message, but this change was not applied to the configuration of the `detect_exceptions` plugin, so currently no collation of exception lines is happening.
This change fixes the issue by changing the field the `detect_exceptions` plugin is using.
**Special notes for your reviewer**:
**Release note**:
```release-note
Fixed exception detection in fluentd-gcp plugin.
```
Without that the daemonset "metadata-agent" return:
```pods "metadata-agent-" is forbidden: unable to validate against any pod security policy: [spec.containers[0].securityContext.containers[0].hostPort: Invalid value: 8799: Host port 8799 is not allowed to be used. Allowed ports: []]```

update fluentd-elasticsearch addon
**What this PR does / why we need it**:
Elastic now provides a fully opensource version for their prebuild
docker images (elasticsearch, kibana and so on). To avoid running into
licensing conflicts for this addon example, we should rather use these
images instead of the premium ones (were we also have to disable premium
features manually right now).
This PR updates:
- fluentd from <=1.1.0 to ~>1.1.3
- elasticsearch and kibana from 5.6.2 to 6.2.4
- fluentd-elasticsearch-plugin from 2.4.1 to 2.9.1

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.

Revert #64364 to resurrect rescheduler. More info https://github.com/kubernetes/kubernetes/issues/64725 :)

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.
