Looks like the get-master-root-disk-size() and get-master-disk-size() functions didn't anticipate
clusters bigger than 2K nodes.
In https://github.com/kubernetes/kubernetes/issues/72976 we found out
that 100GB may be not enough for large clusters (5K nodes) when it comes
to master root disk size.
Updating both get-master-root-disk-size() and get-master-disk-size() to
make them consistent and match cluster sizes with get-master-size()
function.
Currently, only kubernetes-server-linux-<arch>.tar.gz will be downloaded
and staged for tests. It is not possible to test a cluster where the
platform/arch of the nodes differs from that of the master
control-plane. This changes allows downloading and staging node
binaries, in addition to the existing server binaries.
This change renames the '--experimental-encryption-provider-config'
flag to '--encryption-provider-config'. The old flag is accepted but
generates a warning.
In 1.14, we will drop support for '--experimental-encryption-provider-config'
entirely.

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.

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 firewall config is removed from cluster/gce/util.sh. Variable name sctp_addr is corrected to sctpAddr in pkg/proxy/ipvs/proxier.go

Bug fix: Should allow alias range size equals to max number of pods * 2
**What this PR does / why we need it**:
Currently in gce/config-common.sh, function get-alias-range-size returns a range which is strictly bigger than log2(max pods * 2). Where equal should be also acceptable. Say if max pods constraint = 8, it should return /28, instead of /27.

Add /home/kubernetes/bin into sudoers path, so that `sudo crictl` works.
Add `/home/kubernetes/bin` to sudoers path, so that user can call `sudo crictl` directly.
Without this fix, user has to either use the full path `sudo /home/kubernetes/bin/crictl` or switch to root, which is not a good user experience.

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.
Fixes#62808

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.
This is PR is part of #39845.

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.
