Most code generators inside `staging/` are CLI tools.

fix device name change issue for azure disk: add remount logic

**What this PR does / why we need it**:
fix device name change issue for azure disk: add remount logic

Accoding to [Troubleshoot Linux VM device name change](https://docs.microsoft.com/en-us/azure/virtual-machines/linux/troubleshoot-device-names-problems), there is possibility of device name change, so when kubelet is restarted, we need to check whether the following two paths are still valid:
1. `/var/lib/kubelet/plugins/kubernetes.io/azure-disk/mounts/m358246426`: in MountDevice func
2. `/var/lib/kubelet/pods/950f2eb8-d4e7-11e7-bc95-000d3a041274/volumes/kubernetes.io~azure-disk/pvc-67e4e319-d4e7-11e7-bc95-000d3a041274`: in SetUpAt func

**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 #57952

**Special notes for your reviewer**:
 this is a corresponding fix of https://github.com/kubernetes/kubernetes/pull/57549, #57549 uses '/dev/disk/by-id', and this PR would check whether the mountPath is valid when kubelet restart(e.g.  after VM reboot since device name may change), if not valid, remount,  remember '/dev/disk/by-id' will be always valid.

**Release note**:

```

Explicit kubelet flags

The Kubelet was using the global flag set.
Libraries also often use the global flag set.
There are flags in the Kubelet's usage statement for which the Kubelet does not control registration.
This is bad, we must have full control of our command-line API.
This PR puts a stop to it.

I worked through the Kubelet's usage printout and tracked down the flags. 

In the below list, flags with checkboxes are one of:
- explicitly **registered** in this PR
- thought about and outright **rejected**
- thought about and **registered-deprecated** for legacy reasons

For the others we need to figure out whether they should be **registered** or **rejected** or **registered-deprecated**.

```release-note
The Kubelet now explicitly registers all of its command-line flags with an internal flagset, which prevents flags from third party libraries from unintentionally leaking into the Kubelet's command-line API. Many unintentionally leaked flags are now marked deprecated, so that users have a chance to migrate away from them before they are removed. One previously leaked flag, --cloud-provider-gce-lb-src-cidrs, was entirely removed from the Kubelet's command-line API, because it is irrelevant to Kubelet operation.
```

Thanks to @liggitt for being surprised that we didn't already do this.
Thanks to @dashpole for realizing cadvisor flags were leaked after seeing #55863.
Thanks to @tallclair who recognized this problem a long time ago in #19432.

Note that this PR also marks cpu manager test as `Serial`, because it restarts kubelet during the test. It doesn't cause problem in regular node e2e suite today, because it is skipped if node has less than 2 CPUs, which is the case for our test environment. /cc @balajismaniam
