We need the go struct tags `patchMergeKey` and `patchStrategy`
for fields that support a strategic merge patch. For native
resources, we can easily figure out these tags since we know
the fields.
Because custom resources are decoded as Unstructured and
because we're missing the metadata about how to handle
each field in a strategic merge patch, we can't find the
go struct tags. Hence, we can't easily do a strategic merge
for custom resources.
So we should fail fast and return an error.

fix azure file mount limit issue on windows due to using drive letter
**What this PR does / why we need it**:
It's not necessary to use drive letter in azure file mount, correct usage for New-SmbGlobalMapping is like following:
```
New-SmbGlobalMapping -RemotePath $AzureFilePath -Credential $Credential
mklink /D $mountPath $AzureFilePath
```
I removed the `LocalPath` parameter in New-SmbGlobalMapping
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes#54668
Without this PR, there is a limit(25) for azure file mount number on each node because only 25 drive letters could be used on each windows node, With this PR, there would be no such limit.
**Special notes for your reviewer**:

The current implementation of `CanUseIPVSProxier()` reads `/proc/modules`
to check whether IPVS related kernel modules can be loaded.
You might get a false-negative when the kernel modules are installed to
the system but haven't been loaded into the kernel.
This patch firstly try to run `modprobe` to load specified kernel
modules, then just log warnings if error occured.
Secondly, it will check loaded kernel modules by reading
`/proc/modules`, return an error if any required module is missing.
This change will not break the compatability of existing implementation.
Running kube-proxy in a container without mounting `/lib/modules` will
cause `modprobe` warnings, but not raise an error if all required modules are
present in the host kernel.

**Special notes for your reviewer**:
Added a test case to cover specific issue described.
It fails on version `v1.7.3`..`v1.7.9` and passes since `v1.8.0`.
P.S. Not sure if there is already a lower level test which covers this case in the k8s test suite. I would recommend to add this test, so the issue would not reoccur.
