e2e for cluster-autoscaler unhealthy cluster handling
Add e2e test for cluster-autoscaler handling of unhealthy cluster.
~~This only passes reliably with https://github.com/kubernetes/contrib/pull/2488 and should not be merged before it.~~ (included in current CA image)
**Release note**:
```release-note
```
If we get the scheduling metrics, which is "SchedulingAlgorithmLatency, E2eSchedulingLatency, BindingLatency". The E2eSchedulingLatency should be the sum of SchedulingAlgorithmLatency and BindingLatency, while we found E2eSchedulingLatency is almost the same as E2eSchedulingLatency for some optimization.
Adding test cases for HC updates found a bug with an update that
simultaneously removes one port and adds another. Map iteration is
randomized, so sometimes no HC would be created.
- reuse default framework setup rather than duplicating
- skip namespace creation for each test in hosting cluster
- ensure FederationAfterEach is called if BeforeEach fails

Juju: Enable GPU mode if GPU hardware detected
**What this PR does / why we need it**:
Automatically configures kubernetes-worker node to utilize GPU hardware when such hardware is detected.
layer-nvidia-cuda does the hardware detection, installs CUDA and Nvidia
drivers, and sets a state that the k8s-worker can react to.
When gpu is available, worker updates config and restarts kubelet to
enable gpu mode. Worker then notifies master that it's in gpu mode via
the kube-control relation.
When master sees that a worker is in gpu mode, it updates to privileged
mode and restarts kube-apiserver.
The kube-control interface has subsumed the kube-dns interface
functionality.
An 'allow-privileged' config option has been added to both worker and
master charms. The gpu enablement respects the value of this option;
i.e., we can't enable gpu mode if the operator has set
allow-privileged="false".
**Special notes for your reviewer**:
Quickest test setup is as follows:
```bash
# Bootstrap. If your aws account doesn't have a default vpc, you'll need to
# specify one at bootstrap time so that juju can provision a p2.xlarge.
# Otherwise you can leave out the --config "vpc-id=vpc-xxxxxxxx" bit.
juju bootstrap --config "vpc-id=vpc-xxxxxxxx" --constraints "cores=4 mem=16G root-disk=64G" aws/us-east-1 k8s
# Deploy the bundle containing master and worker charms built from
# https://github.com/tvansteenburgh/kubernetes/tree/gpu-support/cluster/juju/layers

Update boltdb dependency to fix golang 1.7 intermittent failures
We have a old boltdb/bolt, etcd has moved to newer boltdb, so we should
do the same. Specifically this change needs to be in our tree:
92410e0673
as this fixes intermittent issues we see in our CI runs. So in this
PR, we vendor the v1.3.0 version of boltdb/bolt.
Fixes#43973

get-kube-local.sh checks pods with option "--namespace=kube-system"
**What this PR does / why we need it**:
Local cluster creation using get-kube-local.sh is never finished.
The get-kube-local.sh monitors running_count of pods such as etcd,
master and kube-proxy, but these pods are created under the namespace
kube-system. Therefore kubectl can't find these pods then cluster
creation isn't completed.
The get-kube-local.sh should monitor created pods with option
"--namespace=kube-system".
**Which issue this PR fixes** : fixes#42517
**Release note**:
```
`NONE`

Change an Errorf to a Fatalf to prevent a panic.
In #37982 we see that if this error is hit then we will panic on the next line. Lets use `Fatalf` where appropriate :)
This does *not* fix the flake, since that's caused by the test assuming that a particular port is free.

Clearer ImageGC failure errors. Fewer events.
Addresses #26000. Kubelet often "fails" image garbage collection if cAdvisor has not completed the first round of stats collection. Don't create events for a single failure, and make log messages more specific.

Remove 'beta' from default storage class annotation (storage/util)
**What this PR does / why we need it**:
This is a follow up to: #42991 where I believe this file was overlooked.
It removes `beta` from the default storageclass annotation.
Without this fix you are not able to specify a default storage class like this:
```yaml
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
name: standard
annotations:
storageclass.kubernetes.io/is-default-class: "true"
provisioner: kubernetes.io/aws-ebs
parameters:
type: gp2
```
because the annotation is ignored in: https://github.com/kubernetes/kubernetes/blob/master/plugin/pkg/admission/storageclass/default/admission.go#L129

cluster/log-dump - chmod files before dumping
We make the files world-readable, so that installation techniques that
lock down the logfiles can still be dumped.

Use shared informers instead of creating local controllers/reflectors
for the proxy's endpoints and service configs. This allows downstream
integrators to pass in preexisting shared informers to save on memory &
cpu usage.
This also enables the cache mutation detector for kube-proxy for those
presubmit jobs that already turn it on.

Adding more proxy options and header to nginx load-balancer.

Cluster-autoscaler multistep node drain e2e
**What this PR does / why we need it**:
This is another Cluster-Autoscaler node drain test. It tests draining a node, when there is pdb allowing for moving some pods, but not all the required pods in one go. Basically it's a more complex scenario of other CA drain e2e, testing the retry logic in CA scale down.
