Remove e2e-image-puller
**What this PR does / why we need it**:
A long time ago, We added the image prepulling as a workaround due to
the overwhelming amount of flake caused by pulling during the tests.
This functionality has been broken for a while now when we switched to a
COS image where mounting `docker` binary into `busybox` stopped working.
So we just have dead code we should clean up.

Fix an issue about generation of secret key with invalid key size in gce
Replace /dev/random to /dev/urandom to avoid generation of secret key with invalid key size.
**What this PR does / why we need it**:
In GCE env, AESGCM encryption of secrets by default generates a secret key with /dev/random which sometime generates a key with invalid size.
This cause the cluster/kube-up.sh to fail in gce environment.
This PR replaces /dev/random with /dev/urandom to have a secret key generated consistently with right size.

Support extra prune resources in kube-addon-manager.
The default prune whitelist resources in https://github.com/kubernetes/kubernetes/blob/master/pkg/kubectl/cmd/apply.go#L531 are sometimes not enough.
One example is that when we remove an admission webhook running as an addon pod, after we remove the addon yaml file, the admission webhook pod will be pruned, but the `MutatingWebhookConfiguration`/`ValidationWebhookConfiguration` won't... If the webhook failure policy is `Fail`, this will break the cluster, and users can't create new pods anymore.
It would be good to at least make this configurable, so that users and vendors can configure it based on their requirement.
This PR keeps the default prune resource list exactly the same with before, just makes it possible to add extra ones.

**Special notes for your reviewer**:
**Release note**:
```release-note
SCTP is now supported as additional protocol (alpha) alongside TCP and UDP in Pod, Service, Endpoint, and NetworkPolicy.
```
* add snapd_refresh config and handlers to k8s-master and -worker
* lint readmes
* add snapd_refresh doc to the readme; make "max" less specific
* adjust wording to note snapd_refresh only affects store snaps
The requested Service Protocol is checked against the supported protocols of GCE Internal LB. The supported protocols are TCP and UDP.
SCTP is not supported by OpenStack LBaaS. If SCTP is requested in a Service with type=LoadBalancer, the request is rejected. Comment style is also corrected.
SCTP is not allowed for LoadBalancer Service and for HostPort. Kube-proxy can be configured not to start listening on the host port for SCTP: see the new SCTPUserSpaceNode parameter
changed the vendor github.com/nokia/sctp to github.com/ishidawataru/sctp. I.e. from now on we use the upstream version.
netexec.go compilation fixed. Various test cases fixed
SCTP related conformance tests removed. Netexec's pod definition and Dockerfile are updated to expose the new SCTP port(8082)
SCTP related e2e test cases are removed as the e2e test systems do not support SCTP
sctp related firewall config is removed from cluster/gce/util.sh. Variable name sctp_addr is corrected to sctpAddr in pkg/proxy/ipvs/proxier.go
cluster/gce/util.sh is copied from master
Implemented the call to get all cluster objects in a zone for a project.
Also added code to allow the container api to be set in the gce.conf
file.
Requested fix for @lavalamp. Fixed GetClusters to be GetManagedClusters.
Leaving ListClusters as ListClusters as it is part of the Cloud Clusters
interface, despite also being a "managed" call.

Adding IKS functionality to kubemark
**What this PR does / why we need it**:
This PR adds bash scripts in which kubemark is able to be run on IKS clusters. This adds versatility to the testing ability of kubemark by adding another cloud provider and example of use. The scripts to clean up kubemark after use are also included. In addition to this, minor changes were added to other kubemark related files to increase cloud-provider flexibility.
**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
No issues will be fixed, as this is an extension to a feature.
**Special notes for your reviewer**:
I currently have the IKS scripts separate from the default ones, which are mainly based off of GCE. If it is preferable, I could combine them into single scripts which prompt the user to choose which cloud provider to test. If there are any issues with the scripts or code, please let me know. Thank you!
**Release note**:
```release-note
NONE

In addition to the shell script changes the heapster yaml has been

no-op change. The values specified for heapster-nanny reflect the current
configuration used with version 1.8.2.

The underlying issue is that both layer-snap and the kubernetes layers are using `any_file_changed` to look for changes in the resources. This PR fixes it by removing the use of `any_file_changed` in the top-level layers, and implementing our own code for it instead.

Reload systemd config files before starting kubelet.
In some environments, the os image comes with preloaded kubelet.service,
so we need to reload systemctl configs to make changes effective.
**What this PR does / why we need it**:
Some OS images already contains kubelet.service with preloaded kubelet in some random version. After doing changes to kubelet.service we need to call 'systemctl daemon-reload' to make changes effective.

Fixed the wrong elasticsearch node counter
**What this PR does / why we need it**:
I am experiencing the nasty bug during the deployment of the elasticsearch-logging statefulset on my custom Kubernetes in Azure (AzureDisk persistant storage). Let's imaging that we want two master nodes which our elasticsearch will try to find during the discovery procedure. Because of the delay between creation of two nodes (azure disk creation) there will be a situation when only one node exists in the service endpoint list and it will be enough to pass the elasticsearch logging discovery step. Only one node will be written to the elasticsearch.yml, but it expects two. Elasticsearch will not be able to find required two nodes. Then Kubernetes will terminate the first pod while the second pod is almost ready (remove that endpoint from service). Then it adds the ip of the second pod to the endpoint and discovery fails as well. This is the endless procedure.

Fix exception detection in new version of fluentd-gcp addon
**What this PR does / why we need it**:
The `detect_exceptions` plugin is used to group log entries that belong to a common exception together into one log message. A [recent change](1ca851baec/cluster/addons/fluentd-gcp/fluentd-gcp-configmap.yaml (L100)) to the configuration modified which field is used for the log message, but this change was not applied to the configuration of the `detect_exceptions` plugin, so currently no collation of exception lines is happening.
This change fixes the issue by changing the field the `detect_exceptions` plugin is using.

Usage of names containing uppercase characters returned by calls to

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.

Use default seccomp profile for GCE manifests
**What this PR does / why we need it**:
This PR sets the default seccomp profile of unprivileged addons to 'docker/default' for GCE manifests. This PR is a followup of #62662. We are using 'docker/default' instead of 'runtime/default' in addons in order to handle node version skew. When seccomp profile is applied automatically by default later, we can remove those annotations.

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.
/cc @bsalamat @aveshagarwal @k82cn
Please let me know your thoughts on this.
```release-note
Revert #64364 to resurrect rescheduler. More info https://github.com/kubernetes/kubernetes/issues/64725 :)

Use default seccomp profile for flutend-elasticsearch addons
**What this PR does / why we need it**:
This PR sets the default seccomp profile to 'docker/default' for:
- fluentd-es daemon set.

The elasticsearch-logging stateful set is still unconfined because it uses gce:podsecuritypolicy:privileged.
This PR is a followup of #62662. We are using 'docker/default' instead of 'runtime/default' in addons in order to handle node version skew. When seccomp profile is applied automatically by default later, we can remove those annotations.
