Disable default paging in list watches
For 1.8 this will be off by default. In 1.9 it will be on by default.
Add tests and rename some fields to use the `chunking` terminology.
Note that the pager may be used for other things besides chunking.
Follow on to #48921, we left the field on to get some exercise in the normal code paths, but needs to be disabled for 1.8.

GCE: Bubble IP reservation error to the user when the address is specified.
This PR improves the debug-ability of internal load balancers when an IP fails to be reserved. I'm mostly worried about the case when the subnetwork URL is wrong or referencing a shared network from another project which isn't yet supported. As you can see from line 160, I had originally planned to surface the reservation error, but printed the wrong error.

Pipe in upgrade image target for kube-proxy migration tests
**What this PR does / why we need it**:
https://k8s-testgrid.appspot.com/sig-network#gci-gce-latest-upgrade-kube-proxy-ds&width=20
and
https://k8s-testgrid.appspot.com/sig-network#gci-gce-latest-downgrade-kube-proxy-ds&width=20
are still failing.
Reproduced it locally and found node image is being default to debian during upgrade (it was gci before upgrade) because we don't pass in `gci` via `--upgrade--target`. And for some reasons (haven't figured out yet), the upgraded node uses debian image with gci startupscripts...
This PR pipes in `--upgrade-target` for kube-proxy migration tests, hopefully in conjunction with https://github.com/kubernetes/test-infra/pull/4447 it will bring the tests back to normal.

do not update init containers status if terminated
fixes#29972#41580
This fixes an issue where, if a completed init container is removed while the pod or subsequent init containers are still running, the status for that init container will be reset to `Waiting` with `PodInitializing`.
This can manifest in a number of ways.
If the init container is removed why the main pod containers are running, the status will be reset with no functional problem but the status will be reported incorrectly in `kubectl get pod` for example
If the init container is removed why a subsequent init container is running, the init container will be **re-executed** leading to all manner of badness.

Fix proxied request-uri to be valid HTTP requests
Fixes#52022, introduced in 1.7. Stringifying/re-parsing the URL masked that the path was not constructed with a leading `/` in the first place.

StatefulSet: Deflake e2e RunHostCmd.
The initial retry up to 20s was giving up too soon. I'm seeing this test flake because the Node rebooted and it takes ~2min to recover. Now StatefulSet RunHostCmd calls will use the same 5min timeout as with other Pod state checks.

Fix setNodeAddress when a node IP and a cloud provider are set
**What this PR does / why we need it**:
When a node IP is set and a cloud provider returns the same address with
several types, only the first address was accepted. With the changes made
in PR #45201, the vSphere cloud provider returned the ExternalIP first,
which led to a node without any InternalIP.
The behaviour is modified to return all the address types for the
specified node IP.
**Which issue this PR fixes**: fixes#48760
**Special notes for your reviewer**:
* I'm not a golang expert, is it possible to mock `kubelet.validateNodeIP()` to avoid the need of real host interface addresses in the test ?
* It would be great to have it backported for a next 1.6.8 release.

Enable CRI-O stats from cAdvisor
**What this PR does / why we need it**:
cAdvisor may support multiple container runtimes (docker, rkt, cri-o, systemd, etc.)
As long as the kubelet continues to run cAdvisor, runtimes with native cAdvisor support may not want to run multiple monitoring agents to avoid performance regression in production. Pending kubelet running a more light-weight monitoring solution, this PR allows remote runtimes to have their stats pulled from cAdvisor when cAdvisor is registered stats provider by introspection of the runtime endpoint.
See issue https://github.com/kubernetes/kubernetes/issues/51798
**Special notes for your reviewer**:
cAdvisor will be bumped to pick up https://github.com/google/cadvisor/pull/1741
At that time, CRI-O will support fetching stats from cAdvisor.

Charges quota only for initialized objects
Partially fix https://github.com/kubernetes/kubernetes/issues/51842.
Based on https://github.com/kubernetes/kubernetes/pull/51733/files. Only the commit "Don't charge quota when creating/updating an uninitialized object" is new.
The old plan was to charge quota for each update of uninitialized object. This PR makes the quota admission only charges the update that removes the last pending initializer. Because
* https://github.com/kubernetes/kubernetes/pull/51247, which lets sharedInformer see uninitialized objects, is not making the code freeze deadline. Hence, the quota replenishing controller won't capture deletion of uninitialized objects. We will leak quota if we charge quota for uninitialized objects.
* @lavalamp @erictune pointed out calculating/reserving quota is expensive, we should avoid doing it for every initializer update.
* My original argument was that quota admission should fail early so that user can easily figure out which initializer causes the quota outage. @lavalamp @erictune convinced me that user could easily figure the culprit if they watch the initialization process.

Implement StatsProvider interface using CRI stats
Ref: https://github.com/kubernetes/kubernetes/issues/46984
This is the follow up of https://github.com/kubernetes/kubernetes/pull/50932
- I include the cadvisor dependency changes in this PR for now to make it build. @dashpole will update the cadvisor dependency very soon, and I will remove the change once it's updated.
- Please take a closer look at the implementation in `cri_stats_provider.go` since we currently don't have any runtime implementing the CRI stats interface and the changes here cannot be enabled in e2e tests.
- Pod level network stats and container level logs stats are not provided.
- In `cadvisor_stats_provider.go`, we are able to remove the call to `getCgroupStats` in `ImageFsStats` for getting the timestamp of the stats, given that we've changed cadvisor to include the timestamp in `FsInfo`.
- Fixed the usage of `assert.Equal` in unit tests.
**Release note**:
```
Support getting container stats from CRI.

add controller permissions to set blockOwnerDeletion

`blockOwnerDeletion` requires delete permissions on the owner object. This adds that permission for our controllers.

```release-note
The OwnerReferencesPermissionEnforcement admission plugin now requires `update` permission on the `finalizers` subresource of the referenced owner in order to set `blockOwnerDeletion` on an owner reference.
```
The feature is still Alpha and at times, the IP address previously used
by the load balancer in the test will not completely freed even after
the load balancer is long gone. In this case, the test URL with the IP
would return a 404 response. Tolerate this error and retry until the new
load balancer is fully established.
