Refactor persistent volume controller

Here is complete persistent controller as designed in https://github.com/pmorie/pv-haxxz/blob/master/controller.go

It's feature complete and compatible with current binder/recycler/provisioner. No new features, it *should* be much more stable and predictable.

Testing
--
The unit test framework is quite complicated, still it was necessary to reach reasonable coverage (78% in `persistentvolume_controller.go`). The untested part are error cases, which are quite hard to test in reasonable way - sure, I can inject a VersionConflictError on any object update and check the error bubbles up to appropriate places, but the real test would be to run `syncClaim`/`syncVolume` again and check it recovers appropriately from the error in the next periodic sync. That's the hard part.

Organization
---
The PR starts with `rm -rf kubernetes/pkg/controller/persistentvolume`. I find it easier to read when I see only the new controller without old pieces scattered around.
[`types.go` from the old controller is reused to speed up matching a bit, the code looks solid and has 95% unit test coverage].

I tried to split the PR into smaller patches, let me know what you think.

~~TODO~~
--

* ~~Missing: provisioning, recycling~~.
* ~~Fix integration tests~~
* ~~Fix e2e tests~~

Jan Safranek 1d0b1c227b Add PV.Name into names of generated GCE/AWS/OSP volumes. 
Volume names have now format <cluster-name>-dynamic-<pv-name>.

pv-name is guaranteed to be unique in Kubernetes cluster, adding
<cluster-name> ensures we don't conflict with any running cluster
in the cloud project (kube-controller-manager --cluster-name=XXX).

'kubernetes' is the default cluster name.

Jan Safranek 76b6449715 Retry recycle or delete operation on failure. 
Recycle controller tries to recycle or delete a PV several times.
It stores count of failed attempts and timestamp of the last attempt in
annotations of the PV.

By default, the controller tries to recycle/delete a PV 3 times in
10 minutes interval. These values are configurable by
kube-controller-manager --pv-recycler-maximum-retry=X --pvclaimbinder-sync-period=Y
arguments.
