Fix windows UT for proxy mode

**What this PR does / why we need it**:

/kind bug

Fix windows UT for proxy mode.

Run UTs for `kubeproxyconfig/validation` in windows,

```
=== RUN   TestValidateKubeProxyConfiguration
--- FAIL: TestValidateKubeProxyConfiguration (0.00s)
        validation_test.go:83: expected success: [KubeProxyConfiguration.Mode.ProxyMode: Invalid value: "ipvs": must be kernelspace,userspace or blank (blank means the most-available proxy [currently userspace])]
```

That's because proxy mode "IPVS" is not valid in windows.

add "Not Found" error for ipset set & entry delete

**What this PR does / why we need it**:

Add "not found error" for ipset set and entry delete. For example,

```

[root@SHA1000130405 k8s-yml]# ipset delete foo
ipset v6.19: The set with the given name does not exist

[root@SHA1000130405 k8s-yml]# ipset del KUBE-LOOP-BACK 1.2.3.4,tcp:80,1.2.3.4
ipset v6.19: Syntax error: Third element is missing from 1.2.3.4,tcp:80,1.2.3.4.
```
Just need to filter the error message "does not exist" or "element is missing". We should ignore these error when try to make sure they are deleted.

replace syscall with sys/unix pkg in ipvs/netlink call

**What this PR does / why we need it**:

This PR replaces syscall with sys/unix pkg in ipvs/netlink call as the Go doc for syscall says:

	NOTE: This package is locked down.
	Code outside the standard Go repository should be migrated to use the corresponding package in the golang.org/x/sys repository.
	That is also where updates required by new systems or versions should be applied.
	See https://golang.org/s/go1.4-syscall for more information.

Fix ipvs proxier nodeport

**What this PR does / why we need it**:

Fix ipvs proxier nodeport.

**Which issue(s) this PR fixes**:
Fixes #55923 

**Special notes for your reviewer**:

We bump the netwlink version in the 1st commit because:

* We call `netlink.RouteListFiltered()` to filter LOCAL type addresses from kernel route table. `netlink.RouteListFiltered()` exists in newer-version netlink package


* newer-version netlink package migrate `syscall` to `golang.org/x/sys/unix`, k8s cross-build can benefit from it as well. The Go doc for syscall says:

> NOTE: This package is locked down. Code outside the standard Go repository should be migrated to use the corresponding package in the golang.org/x/sys repository. That is also where updates required by new systems or versions should be applied. See https://golang.org/s/go1.4-syscall for more information.

Remove dead code in winkernel proxy UT

**What this PR does / why we need it**:

There is a `+build windows` tag in `pkg/proxy/winkernel/proxier_test.go`, it means the UTs will not run in upstream CI. Plus, the UT codes in  `pkg/proxy/winkernel/proxier_test.go` are not for winkernel proxier, instead they are for iptables proxier!

We should remove the dead code in winkernel proxy UT and then create the winkernel-specific UTs.

Add IPv6 and negative UT test cases for proxier's deleteEndpointConnections

This change adds IPv6 and negative UT test cases for the proxier's deleteEndpointConnections.

Changes include:
- Add IPv6 UT test cases to TestDeleteEndpointConnections.
- Add negative UT test case to TestDeleteEndpointConnections for
  handling case where no connections need clearing (benign error).
- Add negative UT test case to test unexpected error.
- Reorganize UT in TestDeleteEndpointConnections so that the fake
  command executor's command and scripted responses are generated on
  the fly based on the test case table (rather than using a fixed
  set of commands/responses that will need to be updated every time
  test cases are added/deleted).
- Create the proxier service map in real time, based on the test case
  table (rather than using a fixed service map that will need to be updated
  every time test cases are added/deleted).

fixes #53554

Implement dummy device operation by netlink for ipvs proxier

**What this PR does / why we need it**:

Currently, we implement network interface operations, e.g. create a dummy device and delete a dummy interface via ip cmd and then collect the exist code. For example, we assume the following command:
```
ip link add kube-ipvs0 type dummy 
```
returns 2 means the dummy device `kube-ipvs0` exists, see https://github.com/kubernetes/kubernetes/blob/master/pkg/proxy/ipvs/proxier.go#L1529 .

However, from the man page of ip command, exit status 2 just means an error was reported by the kernel, see http://man7.org/linux/man-pages/man8/ip.8.html#EXIT_STATUS.

So, that's a bug.

This PR implements dummy device operation by netlink for ipvs proxier so that can get ride of ip command operations.

Restore kube-proxy's support for 0 values for conntrack settings

**What this PR does / why we need it**: re-allow 0 values for kube-proxy conntrack min, max, max per core, tcp close wait timeout, tcp established timeout.

**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
Fixes #50787

**Special notes for your reviewer**:
- I adjusted validation to allow for 0 values for some of the conntrack settings, as otherwise the "leave the limit as-is" logic wouldn't be allowed.
- I moved the loading of the config file from the cobra command's Validate method to Complete. This way, the config is fully resolved before validation happens. Otherwise, it just validates the default config values first, and _then_ the config is loaded.
- I think I got all the default values & nil checking correct, but please review carefully!

**Release note**:

```release-note

Andy Goldstein ea78586832 Re-allow 0 for kube-proxy conntrack settings
When kube-proxy was refactored to use a configuration file, the ability
to use 0 for conntrack min, max, max per core, and tcp timeouts was
inadvertently broken; if you specified 0, it would instead apply the
default value from defaults.go.

This change restores the ability to use 0 to mean 0.
