01b20d8e77 Generate shorter provisioned PV names. 
GCE PD names are generated out of provisioned PV.Name, therefore it should be
as short as possible and still unique.

79b91b9ee0 Refactor persistent volume initialization 
There should be only one initialization function, shared by the real
controller and unit tests.

7f549511e2 Big move and rename 
- remove persistentvolume_ prefix from all files
- split controller.go into controller.go and controller_base.go (to have them
  under 1500 lines for github)

c5fe1f943c Fixed binder logging 
- we need the original volume/claim in error paths
- don't report version conflicts as errors (they happen pretty often and we
  recover from them)

41adcc5496 Speed up binding of provisioned volumes 
This fixes e2e test for provisioning - it expects that provisioned volumes
are bound quickly.

Majority of this patch is update of test framework needs to initialize the
controller appropriately.

92dc159ab6 Delete provisioned volumes that are not needed. 
We should delete volumes that are provisioned for a claim and the claim
gets bound to different volume during the provisioning.

22e68d4622 recycler: unit tests 
- 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.

cf68370371 recycler: Maintain a list of long-running operations. 
We need to keep list of running recyclers, deleters and provisioners in
memory in order not to start a new recycling/deleting/provisioning twice
for the same volume/claim.

This will be eventually replaced by GoRoutineMap from PR #24838.

prevent nil pointer when starting controllers before running the shar…

Fixes https://github.com/kubernetes/kubernetes/issues/25643.

https://github.com/kubernetes/kubernetes/pull/23795 changed initialization order, so the controller isn't guaranteed to be present at startup.

@mqliang @wojtek-t I'm pretty sure that we're not guaranteed to get back the correct `cache.Indexer` or `cache.Store` either.  I'll look at re-plumbing the `AddIndexer` path to use the same instance so that its safe to use again.

- adapt to framework.NewIndexerInformer instead of using custom cache.

Horizontal autoscalaer tolerance breaching verifier

@piosz @jszczepkowski This is the original HPA test without the other modifications, it makes explicit the mathematics of the logic in case changes ever occur.
