Use chroot for containerized mounts
This PR is to modify the containerized mounter script to use chroot
instead of rkt fly. This will avoid the problem of possible large number
of mounts caused by rkt containers if they are not cleaned up.

Bump gcr.io/google-containers/rescheduler to v0.2.2
**What this PR does / why we need it**: updates the rescheduler image to one based on busybox instead of ubuntu-slim. Changes for the image were in https://github.com/kubernetes/contrib/pull/2390.
Do you think this merits a release note? I'm leaning towards no.
**Release note**:
```release-note
Update gcr.io/google-containers/rescheduler to v0.2.2, which uses busybox as a base image instead of ubuntu.
```

Turn fluentd supervisor off for fluentd-gcp
By default, turn fluentd supervisor off so that when fluentd process fails, for example due to OOM, container fails completely and it would be easy to detect.

Update kubectl in addon-manager to use HPA in autoscaling/v1
Addon-manager is broken since HPA objects were removed from extensions api group.
Came across the logs from [the latest addon-manager on Jenkins](https://storage.googleapis.com/kubernetes-jenkins/logs/ci-kubernetes-e2e-gci-gce/4290/artifacts/bootstrap-e2e-master/kube-addon-manager.log):
```

```
And notice this commit (f66679a4e9) came in two weeks ago, which removed HorizontalPodAutoscaler from extensions/v1beta1.
Addon-manager is now partially functioning that it could successfully create and update addons, but will fail to prune objects, which means upgrade tests may mostly fail.
Pushed another version of addon-manager with kubectl v1.6.0-alpha.2 ([release 2 days ago](https://github.com/kubernetes/kubernetes/releases/tag/v1.6.0-alpha.2)) for fixing, including below images:
- gcr.io/google-containers/kube-addon-manager:v6.4-alpha.2
- gcr.io/google-containers/kube-addon-manager-amd64:v6.4-alpha.2
- gcr.io/google-containers/kube-addon-manager-arm:v6.4-alpha.2

Add ability to enable cache mutation detector in GCE
Add the ability to enable the cache mutation detector in GCE. The current default behavior (disabled) is retained.
When paired with https://github.com/kubernetes/test-infra/pull/1901, we'll be able to detect shared informer cache mutations in gce e2e PR jobs.
Allow cache mutation detector enablement by PRs in an attempt to find
mutations before they're merged in to the code base. It's just for the
apiserver and controller-manager for now. If/when the other components
start using a SharedInformerFactory, we should set them up just like
this as well.

fluentd-gcp: Add kube-apiserver-audit.log.
**What this PR does / why we need it**:
Add `kube-apiserver-audit.log` from https://github.com/kubernetes/kubernetes/pull/41211 to fluentd config, so the audit log gets sent to the same place as `kube-apiserver.log`.
**Which issue this PR fixes**:
**Special notes for your reviewer**:
We would like to backport this to release-1.5 also.
**Release note**:
```release-note
The apiserver audit log (`/var/log/kube-apiserver-audit.log`) will be sent through fluentd if enabled.

cluster/gce: Add env var to enable apiserver basic audit log.
For now, this is focused on a fixed set of flags that makes the audit
log show up under /var/log/kube-apiserver-audit.log and behave similarly
to /var/log/kube-apiserver.log. Allowing other customization would
require significantly more complex changes.
Audit log rotation is handled the same as for `kube-apiserver.log`.

**Release note**:
```release-note
The kube-apiserver [basic audit log](https://kubernetes.io/docs/admin/audit/) can be enabled in GCE by exporting the environment variable `ENABLE_APISERVER_BASIC_AUDIT=true` before running `cluster/kube-up.sh`. This will log to `/var/log/kube-apiserver-audit.log` and use the same `logrotate` settings as `/var/log/kube-apiserver.log`.

Bump up glbc version to 0.9.0-beta.1
I plan to bump up the version to 0.9.0 proper in time for the next 1.5.x release, and cherry-pick both this and the future pr.
Previously we were just using a single version, but the "-beta/alpha" is consistent with how we release kube and gives us a convenient revert target. It also forces us to remove the "beta" tag before code freeze, and track the kubernetes release cycle.
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
