Allow ABAC to be disabled easily on upgrades
**What this PR does / why we need it**:
Adds a local variable to the configure-helper script so that ABAC_AUTHZ_FILE can be set to a nonexistent file in kube-env to disable ABAC on a cluster that previously was using ABAC.

Rename default storageclasses
From UX perspective, 'default' is a bad name for the default storage class:
```
$ kubectl get storageclass
NAME TYPE
default (default) kubernetes.io/aws-ebs
```
This is sort of OK, it gets more confusing when user is not happy with the
preinstalled default storage class and creates its own and makes it default:
```
NAME TYPE
default kubernetes.io/aws-ebs
iops (default) kubernetes.io/aws-ebs
```
This PR uses name of the underlying storage as name of the default storage class:
```
NAME TYPE
gp2 (default) kubernetes.io/aws-ebs
```
On GCE (and many others):
```
NAME TYPE
standard (default) kubernetes.io/gce-pd
```
Detailed list of names of new default storage classes:
* AWS: `gp2`
* GCE: `standard` (from pd-standard)
* vSphere: `thin`
* Cinder does not have a default - it's up to OpenStack admin to set some default and it can change at any time, using `standard` as the class name.
* I was not able to find details about Azure, using `standard` too.

Arrange for elasticsearch to shutdown cleanly
Kubernetes initiates "graceful shutdown" by sending SIGTERM to pid 1, which
is exactly what elasticsearch is expecting (good!)
The way the existing startup scripts worked however, this signal arrived at
the shell wrapper, not elasticsearch, and the shell wrapper exited,
killing the container immediately (bad!)

Create EnsureExists class addons before Reconcile class addons
From #42757.
The addon-manager creates "Reconcile" class addons before creates "EnsureExists" class addons, which is not the best order. The "EnsureExists" class addons tend to be some default configurations like `default-storage-class` and `default kube-dns ConfigMap` (being added in #42757), and we would like to have these default configurations created before other addons are created.

Adds default kube-dns configmap
From #42746.
Using 1.4 kubelet with 1.6 master is causing upgrade test failures. Because kubelet doesn't understand optional configmaps and there is no kube-dns configmap exist, kubelet will crash.
This PR adds an empty kube-dns configmap as an "EnsureExists" class addon for fixing that.
Note: The addon-manager creates "Reconcile" class addons before creates "EnsureExists" class addons, which is not the order we want. I will soon have another PR to reverse this order.
