wait for pod to be fully deleted
**What this PR does / why we need it**:
Fix flaky glusterfs io-streaming tests.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes#49529
**Special notes for your reviewer**:
1) max potential wait for complete pod deletion is ~~15m~~ 5m.
2) ~~removed [Flaky] from HostCleanup, _e2e/node/kubelet.go_ since pod deletion is reliable now.~~
3) ~~added tag [Slow] to HostCleanup due to long max wait for pod deletion.~~
After all CI tests run reliably we can consider removing the [Flaky] tag (2, above), or do that in a separate pr.

Enable API chunking and promote to beta for 1.9
All list watchers default to using chunking. The server by default fills pages to avoid low cardinality filters from making excessive numbers of requests. Fix an issue with continuation tokens where a `../` could be used if the feature was enabled.
```release-note
API chunking via the `limit` and `continue` request parameters is promoted to beta in this release. Client libraries using the Informer or ListWatch types will automatically opt in to chunking.
```
Command line flag API remains the same. This allows ComponentConfig
structures (e.g. KubeletConfiguration) to express the map structure
behind feature gates in a natural way when written as JSON or YAML.
For example:
KubeletConfiguration Before:
```
apiVersion: kubeletconfig/v1alpha1
kind: KubeletConfiguration
featureGates: "DynamicKubeletConfig=true,Accelerators=true"
```
KubeletConfiguration After:
```
apiVersion: kubeletconfig/v1alpha1
kind: KubeletConfiguration
featureGates:
DynamicKubeletConfig: true
Accelerators: true
```

apimachinery: remove ObjectCopier interface(s)
The big commit is a mechanical, transitive removal of the copier interfaces in all structs and function calls.
The etcd3 storage now attempts to fill partial pages to prevent clients
having to make more round trips (latency from server to etcd is lower
than client to server). The server makes repeated requests to etcd of
the current page size, then uses the filter function to eliminate any
matches. After this change the apiserver will always return full pages,
but we leave the language in place that clients must tolerate it.
Reduces tail latency of large filtered lists, such as viewing pods
assigned to a node.

Add launching Cluster Autoscaler in Kubemark
**What this PR does / why we need it**:
Allows to launch Cluster Autoscaler in Kubemark.
To do it, set ENABLE_KUBEMARK_CLUSTER_AUTOSCALER flag to true. This currently only works with one nodegroup, for which you can specify minimum and maximum number of nodes and name. (KUBEMARK_AUTOSCALER_MIN_NODES, KUBEMARK_AUTOSCALER_MAX_NODES, KUBEMARK_AUTOSCALER_MIG_NAME).
Is is important to note that NUM_NODES has a different meaning when launching Cluster Autoscaler - we always start with only one node, but NUM_NODES is used to calculate the size of Kubemark master and addon components.
There are no changes to the current setup if ENABLE_KUBEMARK_CLUSTER_AUTOSCALER is set to false.

This change modifies the way that config.NodeIP is selected at the
start of e2e Networking tests such that if no external addresses are
available from the cloud provider (e.g. either no cloud provider being
used [baremetal or VMs], or the provider doesn't have external IPs
configured), then one of the internal addresses is used.
Without this change, the e2e service-related Networking tests would always
panic when config.ExternalAddrs[0] is accessed and the slice is empty.
This change eliminates the panic, and in some setups, the fallback choice
of using an internal address will provide the necessary connectivity
for the e2e Networking tests to access each node.

- Create a storage class with invalid policy on a VSAN datastore.
- Create a PVC using the above storage class
- Verify if the PVC is not bound.
- Delete the PVC.
- Sleep for 6 minutes so that vSphere Cloud Provider clean up routine can delete the stale dummy VM's.
- Verify if the VM is not present. Otherwise fail the test.

Add ping6 option for e2e ext connectivity test for IPv6-only clusters
e2e tests provide only an (IPv4) ping test for external connectivity.
We need a way to conditionally run a ping6 external connectivity check,

Disable autoscaling before removing autoscaled node pool
This is to prevent flakes due to API calls failing in AfterEach during master restart, which is triggered by deleting an autoscaled node pool. Adding disable call before deleting node pool should prevent this as we'll wait for master restart in disableAutoscaler function.
While it may be faster to wait after deletion of autoscaled node pools, this is less complex and will be easier to remove in the future when changing autoscaling setttings no longer triggers master restart.

Fix sed command to not try shell redirection
RunCmd uses Go's os/exec library to run commands directly. Since these
are not run through a shell, we can't use shell syntax for piping or
file redirection. The proper way to do that is to create a Command
object and set the Std{in,out,err} pipes appropriately. Luckily sed
can handle the behavior we need without having to manually set this up.

Improve PVC ref volume metric test robustness
This test has been flaking. The current working theory is that
volume stats collection didn't run in time to grab the metrics
from the newly created pod.
Made the following changes:
- Added more logs to help debug future failures
- Poll metrics a few additional times before failing the test

Fix broken statefulset e2e test
**What this PR does / why we need it**:
Fixes the CockroachDB statefulset e2e test.
This was broken back in #43637 when the logic in
`(*StatefulSetTester).CreateStatefulSet` switched from using
`generated.ReadOrDie` to read the entire service.yaml file and pass it
to kubectl to using `manifest.SvcFromManifest`, which assumes that the
file contains only a single service.
To fix the test, just remove the second service, which isn't needed to test the Statefulset functionality.

Refactor eviction tests
fixes: #52203
We have a bunch of eviction tests, which each break independently, and take a large amount of time to fix.
This refactors these tests to share the core eviction testing logic. Each tests needs only to set kubelet flags, and specify which pods to run.
I decided to omit the memory eviction tests because they work. Best not to disturb them.
A large portion of the code changes are the renaming of inode_eviction_test.go -> eviction_test.go
This should probably wait until after https://github.com/kubernetes/kubernetes/pull/50392

Remove cloud provider rackspace
**What this PR does / why we need it**:
For now, we have to implement functions in both `rackspace` and `openstack` packages if we want to add function for cinder, for example [resize for cinder](https://github.com/kubernetes/kubernetes/pull/51498). Since openstack has implemented all the functions rackspace has, and rackspace is considered deprecated for a long time, [rackspace deprecated](https://github.com/rackspace/gophercloud/issues/592) ,
after talking with @mikedanese and @jamiehannaford offline , i sent this PR to remove `rackspace` in favor of `openstack`

Fixing E2E Test - After restarting kubelet test expects node's status to be NotReady
**What this PR does / why we need it**:
This PR is fixing the e2e tests involves restarting the kubelets. After the kubelet is restarted, test expect the desired state to be NotReady.
After restarting the kubelet we should wait for some time and then check nodes status to be Ready.
Node should not be checked for NotReady state, after restarting kubelet.

inode eviction tests fill a constant number of inodes
Issue: #52203
inode eviction tests pass often on some OS distributions, and almost never on others. See [these testgrid tests](https://k8s-testgrid.appspot.com/sig-node#kubelet-flaky-gce-e2e&include-filter-by-regex=Inode)
These differences are most likely because different images have fewer or greater inode capacity, and thus percentage based rules (e.g. inodesFree<50%) make the test more stressful for some OS distributions than others.
This changes the test to require that a constant number of inodes are consumed, regardless of the number of inodes in the filesystem, by setting the new threshold to:
nodefs.inodesFree<(current_inodes_free - 200k)
so that after pods consume 200k inodes, they will be evicted. It requires querying the summary API until we successfully determine the current number of free Inodes.

Debug for issues #50945
Aggregator e2e test is intermittantly failing on GKE but not GCE.
Adding the following debugging for help trace issue.
Make sure we always use the same rest client.
Randomly generate the flunder resource name to detect parallel tests.
Print endpoints for sample-system in case multiple instances.
Print original and new pods in case the pod has been restarted.
**What this PR does / why we need it**: Adds debugging for aggregator e2e test to track down GKE flakiness.

Don't specify clusterIP in dns e2e test
**What this PR does / why we need it**:
Different upgrade tests may configure different service clusterIP ranges. If we specify the clusterIP in dns e2e test, it will succeed in one upgrade test but fail in another. This PR doesn't specify clusterIP. It just uses the allocated clusterIP.

This was broken back in #43637 when the logic in
`(*StatefulSetTester).CreateStatefulSet` switched from using
`generated.ReadOrDie` to read the entire service.yaml file and pass it
to kubectl to using `manifest.SvcFromManifest`, which assumes that the
file contains only a single service.

Support kubernetes-anywhere provider
**What this PR does / why we need it**:
Implements a new `kubernetes-anywhere` provider to allow upgrade testing in the e2e binary. This is the final step to allow https://github.com/kubernetes/test-infra/pull/4495 and https://github.com/kubernetes/kubernetes-anywhere/pull/450.
**Which issue this PR fixes**:
https://github.com/kubernetes/kubeadm/issues/311
**Special notes for your reviewer**:
Some questions I had
- Does the `--provider` flag specified [here](dbbf6261e0/jobs/config.json (L8587)) get sent to the flag defined [here](https://github.com/kubernetes/kubernetes/blob/master/test/e2e/framework/test_context.go#L219)? Or should I add another `--provider` flag inside `--upgrade_args` like this: `--upgrade_args=... --provider=kubernetes-anywhere`?
- Is it necessary to add waiting logic after the `make` command, or will it implicitly handle that by itself?
Some other points:
- I chose `sed` to manipulate the current kubernetes-anywhere `.config` rather than duplicating another [`anywhere.go`](https://github.com/kubernetes/test-infra/blob/master/kubetest/anywhere.go). One suggestion was to use `jq` but since the config on disk is not serialized to JSON yet, I'm not sure how that'd work.
- Since I don't have a GCE/GKE account or vCenter, I can't actually verify the e2e binary works. I've managed to build it, but if somebody could quickly run a smoke test, I'd appreciate it. This is my first poke around test-infra and e2e, so there might be some plumbing missing

In autoscaling integration test, use allocatable instead of capacity for node memory
This makes the remaining cluster autoscaling test (integration test of HPA and CA working together to scale up the cluster) use node allocatable resources when computing how much memory we need to consume in order to trigger scale up/prevent scale down. Follow up to #52650 as that one is already merging.

Fix: update system spec to support Docker 17.03
Docker 17.03 is 1.13 with bug fixes so they are of the same minor version release. We've validated them both in https://github.com/kubernetes/kubernetes/issues/42926. This PR changes the system spec to support Docker 17.03.
**This should be in 1.8.**
**Release note**:
```
Kubernetes 1.8 supports docker version 17.03.x.
```
