saad-ali 8f666d9e41 Modify kubelet watcher to support old versions 
Modify kubelet plugin watcher to support older CSI drivers that use an
the old plugins directory for socket registration.
Also modify CSI plugin registration to support multiple versions of CSI
registering with the same name.

Move from glog to klog 
- Move from the old github.com/golang/glog to k8s.io/klog
- klog as explicit InitFlags() so we add them as necessary
- we update the other repositories that we vendor that made a similar
change from glog to klog
  * github.com/kubernetes/repo-infra
  * k8s.io/gengo/
  * k8s.io/kube-openapi/
  * github.com/google/cadvisor
- Entirely remove all references to glog
- Fix some tests by explicit InitFlags in their init() methods

hui luo 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.

Jan Safranek 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.

Add a file store utility package in kubelet

More and more components checkpoints (i.e., persist their states) in
kubelet. Refurbish and move the implementation in dockershim to a
utility package to improve code reusability.

Clayton Coleman 5649f9a578 Move pkg/kubelet/util/csr into client-go 
Everything else it depends on was already there, and now we have a
somewhat consistent code chain.

Have the certificate manager decide if the server is healthy 
Prevent a Kubelet from shutting down when the server isn't responding to
us but we cannot get a new certificate. This allows a cluster to coast
if the master is unresponsive or a node is partitioned and their client
cert expires.

cache.ListWatchUntil should return err.ErrWaitTimeout 
Clients shouldn't have to know about watch.ErrWatchClosed, which is
typically a server side decision to close and always means "Timeout" in
this conetxt.

An expired certificate is not compatible 
If the certificate in the CSR is expired, it's no good to the code.
Error out with the correct message.
