Update busybox dependency to fix bazel build
**What this PR does / why we need it**: the upstream busybox deb has been updated, and the old one no longer exists. This fixes the bazel build for users who haven't already downloaded the old deb into their workspace.
**Special notes for your reviewer**: we really need to figure out a better long-term strategy for this. The release branches are broken now too, and I don't want to have to cherry-pick fixes like this everywhere.

install/kube-up: fix some errors while install k8s through kube-up/down.sh
What this PR does / why we need it:
etcd2.3.1 will be installed follow this scripts, but k8s use etcd3 as default storage backend, so the next error will always be apprear:
API server: rpc error: code = 13 desc = transport is closing
so i think we should change the version of etcd

Extract GCEPD pv tests
**What this PR does / why we need it**:
This is strictly a refactor moving the GCEPD suite in Persistent Volumes E2E to it's own file. This will make future provider specific additions to pv testing much more organized and readable. It will also enable a smoother transition to providers moving out of tree by consolidating related tests.

Update algorithm of equivalence class cache predicates
NOTE: This is the first two commits of #36238
**What's in this PR:**
1. Definition of equivalence class
2. An update of `equivalence_cache.go` algorithms to implement enable/disable equivalence cache for individual predicate
3. Added equivalence class data structure to `Generic Scheduler` but did not initialize it. This is used to show how we will use equivalence class when scheduling.
**Why I did this:**
Although #36238 has been finished for a period of time, we found it's still very hard to review, because it mixed 1) definition of equivalence class, 2) how to use equivalence cache, and 3) how to keep this cache up-to-date, 4) e2e tests to verify (3) works.
So reviewers are easily distracted by different technical points like `hash algorithms`, `how to properly use Informer` etc, left the more important equivalence algorithms untouched.
So this PR I only includes 1) and 2), leaves updating this cache in #36238. I can see this part is totally independent from the rest part of it. So we can definitely review this equivalence strategies first.

Fix problems of not-starting image pullers
In e2e.go there are the following lines:
https://github.com/kubernetes/kubernetes/blob/master/test/e2e/e2e.go#L150
```
if err := framework.WaitForPodsSuccess(c, metav1.NamespaceSystem, framework.ImagePullerLabels, imagePrePullingTimeout); err != nil {
// There is no guarantee that the image pulling will succeed in 3 minutes
// and we don't even run the image puller on all platforms (including GKE).
// We wait for it so we get an indication of failures in the logs, and to
// maximize benefit of image pre-pulling.
framework.Logf("WARNING: Image pulling pods failed to enter success in %v: %v", imagePrePullingTimeout, err)
}
```
However, few lines above:
https://github.com/kubernetes/kubernetes/blob/master/test/e2e/e2e.go#L143
we were waiting for all image pullers to actually enter Success state. It's pretty clear that the latter wasn't expected.
This PR is fixing this problem.

Move cluster logging tests to a separate folder

Use ProviderID to address nodes in the cloudprovider
The cloudprovider is being refactored out of kubernetes core. This is being
done by moving all the cloud-specific calls from kube-apiserver, kubelet and
kube-controller-manager into a separately maintained binary(by vendors) called
cloud-controller-manager. The Kubelet relies on the cloudprovider to detect information
about the node that it is running on. Some of the cloudproviders worked by
querying local information to obtain this information. In the new world of things,
local information cannot be relied on, since cloud-controller-manager will not
run on every node. Only one active instance of it will be run in the cluster.
Today, all calls to the cloudprovider are based on the nodename. Nodenames are
unqiue within the kubernetes cluster, but generally not unique within the cloud.
This model of addressing nodes by nodename will not work in the future because
local services cannot be queried to uniquely identify a node in the cloud. Therefore,
I propose that we perform some(to start off with) of the cloudprovider calls based on
ProviderID. This ID is a unique identifier for identifying a node on an external database (such as
the instanceID in aws cloud).
In the next PR, i'll add support to initialize nodes from the cloud-controller-manager instead of the kubelet using this API.

VSAN policy support for storage volume provisioning inside kubernetes
The vsphere users will have the ability to specify custom Virtual SAN Storage Capabilities during dynamic volume provisioning. You can now define storage requirements, such as performance and availability, in the form of storage capabilities during dynamic volume provisioning. The storage capability requirements are converted into a Virtual SAN policy which are then pushed down to the Virtual SAN layer when a storage volume (virtual disk) is being created. The virtual disk is distributed across the Virtual SAN datastore to meet the requirements.
For example, User creates a storage class with VSAN storage capabilities:
> kind: StorageClass
> apiVersion: storage.k8s.io/v1beta1
> metadata:
> name: slow
> provisioner: kubernetes.io/vsphere-volume
> parameters:
> hostFailuresToTolerate: "2"
> diskStripes: "1"
> cacheReservation: "20"
> datastore: VSANDatastore
The vSphere Cloud provider provisions a virtual disk (VMDK) on VSAN with the policy configured to the disk.
When you know storage requirements of your application that is being deployed on a container, you can specify these storage capabilities when you create a storage class inside Kubernetes.

remove legacy insecure port options from genericapiserver
The insecure port has been a source of problems and it will prevent proper aggregation into a cluster, so the genericapiserver has no need for it. In addition, there's no reason for it to be in the main kube-apiserver flow either. This pull removes it from genericapiserver and removes it from the shared kube-apiserver code. It's still wired up in the command, but its no longer possible for someone to mess up and start using in mainline code.
