**Special notes for your reviewer**:
For each test, launch a pod for each node to setup volumes when needed.
It uses `nsenter` to enter into host mount namespace to run commands.
Why using `nsenter` command:
- migrate to use hostexec pod (baseimage: alpine:3.6) busybox `losetup` is hard
- alpine does not contain mkfs.ext4 command
- easier to setup local volumes (no need to mount /tmp, /mnt, /dev/, /sys directories)
- only require hostexec pod contains `nsenter` command

Usage of names containing uppercase characters returned by calls to
gethostname and getfqdn in requests to apiserver related to nodes
results in 404 errors. Node names are lowercase in K8s itself so charms
should make sure to use lowercase names well as it results in errors.
pkg/util/node/node.go has code to convert hostnames to lowercase in
GetHostname and that function is used to form node names.
For get, condense completions and success into a single column, and
print the job duration. Use a new variant of ShortHumanDuration that
shows more significant digits, since duration matters more for jobs.
```
NAME COMPLETIONS DURATION AGE
image-mirror-origin-v3.10-1529985600 1/1 47s 42m

image-pruner-1529971200 1/1 60m 4h

The completions column can be:
```
COMPLETIONS
0/1 # completions nil or 1, succeeded 0
1/1 # completions nil or 1, succeeded 1
0/3 # completions 3, succeeded 1
1/3 # completions 3, succeeded 1

OpenStack LBaaS fix: must use ID, not name, of the node security group
This is a bugfix for the OpenStack LBaaS cloud provider security group management.
A bit of context: When creating a load balancer for a given `type: LoadBalancer` service, the provider will try to:
(see `pkg/cloudprovider/providers/openstack/openstack_loadbalancer.go`/`EnsureLoadBalancer`)
1. create a load balancer (LB) in Openstack with listeners corresponding to the service's ports
2. attach a floating IP to the LB's network port
If `manage-security-groups` is enabled in controller-manager's cloud.conf:
3. create a security group with ingress rules corresponding to the LB's listeners, and attach it to the LB's network port
4. for all nodes of the cluster, pick an existing security group for the nodes ("node security group") and add ingress rules to it exposing the service's NodePorts to the security group created in step 3.
In the current upstream master, steps 1 through 3 work fine, step 4 fails, leading to a service that's not accessible via the LB without further manual intervention.
The bug is in the "pick an existing security group" operation (func `getNodeSecurityGroupIDForLB`), which, contrary to its name, will return the security group's name rather than its ID (actually it returns a list of names rather than IDs, apparently to cover some corner cases where you might have more than one node security group, but anyway). This will then be used when trying to add the ingress rules to the group, which the Openstack API will reject with a 404 (at least on our (fairly standard) Openstack Ocata installation) because we're giving it a name where it expects an ID.
The PR adds a "get ID given a name" lookup to the `getNodeSecurityGroupIDForLB` function, so it actually returns IDs. That's it. I'm not sure if the upstream code wasn't really tested, or maybe other people use other Openstacks with more lenient APIs. The bug and the fix is always reproducible on our installation.
**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#58145
**Special notes for your reviewer:**
Should we turn `getNodeSecurityGroupIDForLB` into a method with the lbaas as its receiver because it now requires two of the lbaas's attributes? I'm not sure what the conventions are here, if any.

Migrate cpumanager to use checkpointing manager
**What this PR does / why we need it**:
This PR migrates `cpumanager` to use new kubelet level node checkpointing feature (#56040) to decrease code redundancy and improve consistency.
**Which issue(s) this PR fixes**:
Fixes#58339
**Notes**:
At point of submitting PR the most straightforward approach was used - `state_checkpoint` implementation of `State` interface was added. However, with checkpointing implementation there might be no point to keep `State` interface and just use single implementation with checkpoint backend and in case of different backend than filestore needed just supply `cpumanager` with custom `CheckpointManager` implementation.

it traverses and watch plugin directory and its sub directory recursively,
plugin socket file only need be unique within one directory,
- plugin socket directory
- |
- ---->sub directory 1
- | |
- | -----> socket1, socket2 ...
- ----->sub directory 2
- |
- ------> socket1, socket2 ...
the design itself allow sub directory be anything,
but in practical, each plugin type could just use one sub directory.
four bonus changes added as below
1. extract example handler out from test, it is easier to read the code
with the seperation.
2. there are two variables here: "Watcher" and "watcher".
"Watcher" is the plugin watcher, and "watcher" is the fsnotify watcher.
so rename the "watcher" to "fsWatcher" to make code easier to
understand.
3. change RegisterCallbackFn() return value order, it is
conventional to return error last, after this change,
the pkg/volume/csi is compliance with golint, so remove it
from hack/.golint_failures
4. refactor errors handling at invokeRegistrationCallbackAtHandler()
to make error message more clear.
