Usage of names containing uppercase characters returned by calls to
gethostname and getfqdn in requests to apiserver related to nodes
results in 404 errors. Node names are lowercase in K8s itself so charms
should make sure to use lowercase names well as it results in errors.
pkg/util/node/node.go has code to convert hostnames to lowercase in
GetHostname and that function is used to form node names.
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: []]```

Increase logexporter timeout and add debug logs
Ref - https://github.com/kubernetes/kubernetes/issues/63030#issuecomment-396335294
So it seems that logexporter isn't running on too many nodes on our 5k node cluster (~40% of nodes). As a result we fallback to ssh-based copying for so many nodes which is slow and hence the job times out. My feeling is it's because of slow scheduling of logexporter pods (and hence quite some nodes didn't even get the chance to run those pods before we delete the daemonset).

Use unix.EpollWait to determine when memcg events are available to be Read
**What this PR does / why we need it**:
This fixes a file descriptor leak introduced in https://github.com/kubernetes/kubernetes/pull/60531 when the `--experimental-kernel-memcg-notification` kubelet flag is enabled. The root of the issue is that `unix.Read` blocks indefinitely when reading from an event file descriptor and there is nothing to read. Since we refresh the memcg notifications, these reads accumulate until the memcg threshold is crossed, at which time all reads complete. However, if the node never comes under memory pressure, the node can run out of file descriptors.
This PR changes the eviction manager to use `unix.EpollWait` to wait, with a 10 second timeout, for events to be available on the eventfd. We only read from the eventfd when there is an event available to be read, preventing an accumulation of `unix.Read` threads, and allowing the event file descriptors to be reclaimed by the kernel.
This PR also breaks the creation, and updating of the memcg threshold into separate portions, and performs creation before starting the periodic synchronize calls. It also moves the logic of configuring memory thresholds into memory_threshold_notifier into a separate file.
This also reverts https://github.com/kubernetes/kubernetes/pull/64582, as the underlying leak that caused us to disable it for testing is fixed here.

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.
