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.
@liggitt let's merge on wednesday.
Rather than just changing the config once to see if dynamic kubelet
config at-least-sort-of-works, this extends the test to check that the
Kubelet reports the expected Node condition and the expected configuration
values after several possible state transitions.
Additionally, this adds a stress test that changes the configuration 100
times. It is possible for resource leaks across Kubelet restarts to
eventually prevent the Kubelet from restarting. For example, this test
revealed that cAdvisor's leaking journalctl processes (see:
https://github.com/google/cadvisor/issues/1725) could break dynamic
kubelet config. This test will help reveal these problems earlier.
This commit also makes better use of const strings and fixes a few bugs
that the new testing turned up.

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.
This makes upgrade requests proxied to pods/services via the API server proxy subresources be valid HTTP requests
```release-note
Fixes an issue with upgrade requests made via pod/service/node proxy subresources sending a non-absolute HTTP request-uri to backends
```

enhance unit tests of advance audit feature
This change addresses comments from @crassirostris
https://github.com/kubernetes/kubernetes/pull/49115#discussion_r133416080
It does three things:
1. use auditinternal for unit test in filter stage
2. add a seperate unit test for Audit-ID http header
3. add unit test for audit log backend
**Release note**:
```
NONE
```
Charge object count when object is created, no matter if the object is
initialized or not.
Charge the remaining quota when the object is initialized.
Also, checking initializer.Pending and initializer.Result when
determining if an object is initialized. We didn't need to check them
because before 51082, having 0 pending initializer and nil
initializers.Result is invalid.

Graduate metrics/v1alpha1 to v1beta1
This introduces v1beta1 of the resource metrics API, previously in alpha.
The v1alpha1 version remains for compatibility with the Heapster legacy version
of the resource metrics API, which is compatible with the v1alpha1 version. It also
renames the v1beta1 version to `resource-metrics.metrics.k8s.io`.
The HPA controller's REST clients (but not the legacy client) have been migrated as well.
Part of kubernetes/features#118.
```release-note
Migrate the metrics/v1alpha1 API to metrics/v1beta1. The HorizontalPodAutoscaler
controller REST client now uses that version. For v1beta1, the API is now known as
resource-metrics.metrics.k8s.io.

Relax update validation of uninitialized pod
Split from https://github.com/kubernetes/kubernetes/pull/50344
Fix https://github.com/kubernetes/kubernetes/issues/47837
* Let the podStrategy to only call `validation.ValidatePod()` if the old pod is not initialized, so fields are mutable.
* Let the podStatusStrategy refuse updates if the old pod is not initialized.

```release-note
Pod spec is mutable when the pod is uninitialized. The apiserver requires the pod spec to be valid even if it's uninitialized. Updating the status field of uninitialized pods is invalid.

Build test targets for all server platforms
**What this PR does / why we need it**:
🤦
I really should have checked this before code freeze, but tbh forgot it in the rush. Also I thought this was the case already...
As part of https://github.com/kubernetes/features/issues/288; these binaries should be built for all server platforms indeed.
This is just a straightforward add to that list.
Can we please get this into v1.8?
There is virtually no risk involved here really...

Add EgressRule to NetworkPolicy
**Which issue this PR fixes**: fixes#50453
**Special notes for your reviewer**:
- Please take a look at the comments for the various types. I tried to mimic some of the language used in the Ingress comments, but I may have mangled some sentences.
- Let me know if I should add some test cases for validation. I have 2-3, and did not think it was necessary to replicate each case already covered in ingress.
**Release note**:

Update Cadvisor Dependency
Fixes: https://github.com/kubernetes/kubernetes/issues/51832
This is the worst dependency update ever...
The root of the problem is the [name change of Sirupsen -> sirupsen](https://github.com/sirupsen/logrus/issues/570#issuecomment-313933276). This means that in order to update cadvisor, which venders the lowercase, we need to update all dependencies to use the lower-cased version. With that being said, this PR updates the following packages:
`github.com/docker/docker`
- `github.com/docker/distribution`
- `github.com/opencontainers/go-digest`
- `github.com/opencontainers/image-spec`
- `github.com/opencontainers/runtime-spec`
- `github.com/opencontainers/selinux`
- `github.com/opencontainers/runc`
- `github.com/mrunalp/fileutils`
- `golang.org/x/crypto`
- `golang.org/x/sys`
- `github.com/docker/go-connections`
- `github.com/docker/go-units`
- `github.com/docker/libnetwork`
- `github.com/docker/libtrust`
- `github.com/sirupsen/logrus`
- `github.com/vishvananda/netlink`
`github.com/google/cadvisor`
- `github.com/euank/go-kmsg-parser`
`github.com/json-iterator/go`
Fixed https://github.com/kubernetes/kubernetes/issues/51832
```release-note
Fix journalctl leak on kubelet restart
Fix container memory rss

Fix incorrect CPU usage metrics with 4.7 kernel
