Enable Node authorizer and NodeRestriction admission in kubemark
xref https://github.com/kubernetes/features/issues/279
We want to ensure scale testing covers use of the authorizer/admission pair that partitions nodes. This includes enabling the authorizer, which populates a graph of existing nodes and pods.
Kubemark is still running all nodes with a single credential, so a follow-up step is to generate unique credentials per node (or enable TLS bootstrapping) and remove the temporary rolebinding added in this PR so the node authorizer is the one authorizing each call by a hollow node.

Set up proxy certs for Aggregator.
Working on fixing https://github.com/kubernetes/kubernetes/issues/43716.
This will create the necessary certificates.
On GCE is will upload those certificates to Metadata.
They are then pulled down on to the kube-apiserver.
They are written to the /etc/src/kubernetes/pki directory.
Finally they are loaded vi the appropriate command line flags.
The requestheader-client-ca-file can be seen by running the following:-
kubectl get ConfigMap extension-apiserver-authentication --namespace=kube-system -o yaml
**What this PR does / why we need it**:
This PR creates a request header CA. It also creates a proxy client cert/key pair.
It causes these files to end up on kube-apiserver and set the CLI flags so they are properly loaded.
Without it the customer either has to set them up themselves or re-use the master CA which is a security vulnerability.
Currently this creates everything on GCE.

Remove e2e-rbac-bindings.
Replace todo-grabbag binding w/ more specific heapster roles/bindings.
Move kubelet binding.
**What this PR does / why we need it**:
The "e2e-rbac-bindings" held 2 leftovers from the 1.6 RBAC rollout process:
- One is the "kubelet-binding" which grants the "system:node" role to kubelet. This is needed until we enable the node authorizer. I moved this to the folder w/ some other kubelet related bindings.
- The other is the "todo-remove-grabbag-cluster-admin" binding, which grants the cluster-admin role to the default service account in the kube-system namespace. This appears to only be required for heapster. Heapster will instead use a "heapster" service account, bound to a "system:heapster" role on the cluster (no write perms), and a "system:pod-nanny" role in the kube-system namespace.
**Which issue this PR fixes**: Addresses part of #39990
**Release Note**:
```release-note
New and upgraded 1.7 GCE/GKE clusters no longer have an RBAC ClusterRoleBinding that grants the `cluster-admin` ClusterRole to the `default` service account in the `kube-system` namespace.
If this permission is still desired, run the following command to explicitly grant it, either before or after upgrading to 1.7:
kubectl create clusterrolebinding kube-system-default --serviceaccount=kube-system:default --clusterrole=cluster-admin

Audit webhook config for GCE
Add a `ADVANCED_AUDIT_BACKEND` (comma delimited list) environment variable to the GCE cluster config to select the audit backend, and add configuration for the webhook backend.
~~Based on the first commit from https://github.com/kubernetes/kubernetes/pull/46557~~
For kubernetes/features#22
Since this is GCE-only configuration plumbing, I think this should be exempt from code-freeze.

Remove Initializers from admission-control in kubernetes-master charm for pre-1.7
**What this PR does / why we need it**:
This fixes a problem with the kubernetes-master charm where kube-apiserver never comes up:
```
failed to initialize admission: Unknown admission plugin: Initializers
```
The Initializers plugin does not exist before Kubernetes 1.7. The charm needs to support 1.6 as well.

Fixes 47182
**What this PR does / why we need it**: Adds some state guards to the idle_status message to speed up the deployment
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes#47182
**Special notes for your reviewer**:
This adds additional state guards of the idle_status method, which will
prevent it from being run until a worker has joined the relationship.
Previous invocations may have some messaging inconsistencies but will reach
eventual consistency once a worker has joined.
This prevents the polling loop from executing too soon, bloating the
installation time by bare-minimum an additional 10 minutes.
**Release note**:
```release-note
Added state guards to the idle_status messaging in the kubernetes-master charm to make deployment faster on initial deployment.

Write audit policy file for GCE/GKE configuration
Setup the audit policy configuration for GCE & GKE. Here is the high level summary of the policy:
- Default logging everything at `Metadata`
- Known write APIs default to `RequestResponse`
- Known read-only APIs default to `Request`
- Except secrets & configmaps are logged at `Metadata`
- Don't log events
- Don't log `/version`, swagger or healthchecks
In addition to the above, I spent time analyzing the noisiest lines in the audit log from a cluster that soaked for 24 hours (and ran a batch of e2e tests). Of those top requests, those that were identified as low-risk (all read-only, except update kube-system endpoints by controllers) are dropped.
I suspect we'll want to tweak this a bit more once we've had a time to soak it on some real clusters.

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.
