220163f67d Fixed races in Cinder volume attach/detach. 
Add a mutex to guard SetUpAt() and TearDownAt() calls - they should not
run in parallel.  There is a race in these calls when there are two pods
using the same volume, one of them is dying and the other one starting.

TearDownAt() checks that a volume is not needed by any pods and detaches the
volume. It does so by counting how many times is the volume mounted
(GetMountRefs() call below).

When SetUpAt() of the starting pod already attached the volume and did not mount
it yet, TearDownAt() of the dying pod will detach it - GetMountRefs() does not
count with this volume.

These two threads run in parallel:

 dying pod.TearDownAt("myVolume")          starting pod.SetUpAt("myVolume")
   |                                       |
   |                                       AttachDisk("myVolume")
   refs, err := mount.GetMountRefs()       |
   Unmount("myDir")                        |
   if refs == 1 {                          |
   |  |                                    Mount("myVolume", "myDir")
   |  |                                    |
   |  DetachDisk("myVolume")               |
   |                                       start containers - OOPS! The volume is detached!
   |
   finish the pod cleanup


Also, add some logs to cinder plugin for easier debugging in the future, add
a test and update the fake mounter to know about bind mounts.

6b2f70d553 Provide a JSON and YAML serializer, and a versioning wrapper 
Add a recognizer that is capable of sniffing content type from data by
asking each serializer to try to decode - this is for a "universal
decoder/deserializer" which can be used by client logic.

Add codec factory, which provides the core primitives for content type
negotiation. Codec factories depend only on schemes, serializers, and
groupversion pairs.

39c7ea57b0 test: make ValidateCount throw an error instead of a log 
We can either fix it here or at every callsite. Every callsite is
currently using this method incorrectly.

4caa8a2c1d Move pod template hash and label adding util functions to their packages. 
These utilities are useful outside Deployments as well, for example
in DaemonSets for DaemonSet updates. So move them to their own util
packages.
