9743cda4a7 Adding Kubelet changes to enable SetHostnameAsFQDN feature 
These changes allow to set FQDN as hostname of pods for pods
that set the new PodSpec field setHostnameAsFQDN to true. The PodSpec
new field was added in related PR.

This is PART2 (last) of the changes to enable KEP #1797 and addresses #91036

817c9ca953 Process plugins found before the ones watched 
Currently, the method `pluginwatcher.traversePluginDir` descends into
a directory adding filesystem watchers and creating synthetic `create`
events when it finds sockets files. However, a race condition might
happen when a recently-added watcher observes a `delete` event in a
socket file before `pluginwatcher.traversePlugindir` itself notices
this file.

This patch changes this behavior by registering watchers on
directories, enqueueing and processing `create` events from sockets
found, and only then processing the events from the registered watchers.

  * github.com/kubernetes/repo-infra
  * k8s.io/gengo/
  * k8s.io/kube-openapi/
  * github.com/google/cadvisor

d04f596829 Add hierarchy support for plugin directory 
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.

5110db5087 Lock subPath volumes 
Users must not be allowed to step outside the volume with subPath.
Therefore the final subPath directory must be "locked" somehow
and checked if it's inside volume.

On Windows, we lock the directories. On Linux, we bind-mount the final
subPath into /var/lib/kubelet/pods/<uid>/volume-subpaths/<container name>/<subPathName>,
it can't be changed to symlink user once it's bind-mounted.
