scheduler: fix validation test
Signed-off-by: sakeven <jc5930@sina.cn>
**What this PR does / why we need it**:
Without setting `Weight`, `ValidatePolicy` will report
```
Priority for extender http://127.0.0.1:8081/extender should have a positive weight applied to it
```
**Besides**, it seems it's not a good way to test ValidatePolicy by```if ValidatePolicy(extenderPolicy) == nil```, because we can't determine specific reason which causes error.
**Special notes for your reviewer**:
**Release note**:
```
NONE

Allow NetworkPolicy.spec updates
ValidateNetworkPolicyUpdate currently prohibits changes to `spec` in an existing NetworkPolicy. We were going to fix this for 1.7 but I forgot to submit this PR after the main PR merged. Too late for 1.7? @thockin @caseydavenport @cmluciano
This only changes networking.NetworkPolicy validation at the moment... Should I change extensions.NetworkPolicy validation too?
Fixes#35911
We should add a test to the e2e NetworkPolicy test for this too if this is going to merge.
**Release note**:
```release-note
As part of the NetworkPolicy "v1" changes, it is also now
possible to update the spec field of an existing
NetworkPolicy. (Previously you had to delete and recreate a
NetworkPolicy if you wanted to change it.)

Kubelet run() should accept partial KubeletDeps
This is used by integrators that want to perform partial overrides of
key interfaces. Refactors the run() method to fit the existing style and
preserve the existing behavior, but allow (for instance) client
bootstrap and cert refresh even when some dependencies are injected.

Allows the proxier to be used on an interface that's not the default route,
otherwise hostIP gets set to the default route interface even if that's
not what the user intended.
If listen IP isn't given, falls back to previous behavior.
This is part 2 of the effort to update ChoseHostInterface() to support IPv6
addresses (as part of issue 44848). This changeset includes:
- Supports finding IPv6 host addresses from default routes (but currently only
provided with IPv4 default routes).
- getRoutes() filters for default routes.
- getFinalIP() checks that IP is in requested family. Uses IsGlobalUnicast(),
instead of explicit tests for loopback, multicast, and link-local IPs.
- getIPFromInterace() checks for family requested.
- chooseHostInterfaceFromRoute()
* Quickly exits, if no default routes.
* Since only getting default routes, no check here.
* Searches all default routes for IPv4 addresses, and then searches all
default routes for IPv6 addresses (for backwards compatibility).
- More coverage in UTs (87.8% vs 62.6%).
- Better testing of error conditions/results.
- Tests for IPv6 IPs, throughout functions.
- Reduced duplicate testing for items tested at lower levels.

Cleanup useless metrics.go for garbagecollector
The metrics of garbagecollector are already published with the
workqueue metrics, so metrics.go is useless, let's cleanup it.
See https://github.com/kubernetes/client-go/blob/master/util/workqueue/metrics.go.

Move the kubelet certificate management code into a single package
Code is very similar and belongs together. Will allow future cert callers to potentially make this more generic, as well as to make it easier reuse code elsewhere.

IPv6 support for getting node IP
As part of ChooseHostInterface(), it will call a function to try to get the
global IP for the host, by looking at all the system interfaces and select
the first IP that is not a loopback, link-local, or point-to-point IP.
This commit does the following:
- Allows IPv6 non-local IPs to be selected.
- IPv4 takes priority (checks all interfaces for IPv4 addresses and
then checks all interfaces for IPv6), for backward compatibility.
- Adds UTs for code coverage (was no coverage of underlying function),
increasing from 62% to 85%.
- Improved logging and reporting for error conditions.
- Minor renaming of functions and variables for readability.
**What this PR does / why we need it**:
This will be part of several PRs to add IPv6 support in apimachinery area for use by Kubernetes. It partially fixes the issue.

kubeadm: Make self-hosting work and split it out to a phase
**What this PR does / why we need it**:
- Removes the old self-hosting code
- Puts the new self-hosting code in `phases/selfhosting`
- The new code reads manifests from disk (static pods)...
- ...mutates the PodSpec as necessary...
- ...and posts the DaemonSet to the API Server...
- ...and waits for it to come up
- Uses DaemonSets for all control plane components
- Creates a `kubeadm alpha phase selfhosting` command that can be invoked against any kubeadm-cluster after install.

Fix invalid Content-Type for 403 error
https://github.com/kubernetes/kubernetes/pull/47384 makes 403 errors return Status Object. However the Content-Type is still "text/plain"
This change fixes it.
Before this change:
kubectl get pods --as=tom
Error from server (Forbidden): {"kind":"Status","apiVersion":"v1","metadata":{},"status":"Failure","message":"pods \"\" is forbidden: User \"tom\" cannot list pods in the namespace \"default\".","reason":"Forbidden","details":{"kind":"pods"},"code":403} (get pods)
After this change:
$ kubectl get pods --as=tom
Error from server (Forbidden): pods "" is forbidden: User "tom" cannot list pods in the namespace "default".
