recycler: unit tests

Browse Source 
- Add reclaim policy to newVolume() call.
- Implement reactor Volumes().Get().
- Implement mock volume plugin.
- Add recycler tests.
- Add a synchronization condition to controller.scheduleOperation
  - we need to pause the controller here, let the test to do some bad things
    to the controller and test error cases in recycleVolumeOperation.

Test framework gets more and more complicated... But this is the last piece,
I promise.
