Michal Rostecki 59ca5986dd Print/log pointers of structs with %#v instead of %+v 
There are many places in k8s where %+v is used to format a pointer
to struct, which isn't working as expected.

Fixes #26591

Justin Santa Barbara dd94997619 Add comments & misc review fixes 
Lots of comments describing the heuristics, how it fits together and the
limitations.

In particular, we can't guarantee correct volume placement if the set of
zones is changing between allocating volumes.

Justin Santa Barbara e711cbf912 GCE/AWS: Spread PetSet volume creation across zones 
Long term we plan on integrating this into the scheduler, but in the
short term we use the volume name to place it onto a zone.

We hash the volume name so we don't bias to the first few zones.

If the volume name "looks like" a PetSet volume name (ending with
-<number>) then we use the number as an offset.  In that case we hash
the base name.

Fixes #27256

saadali 542f2dc708 Introduce new kubelet volume manager 
This commit adds a new volume manager in kubelet that synchronizes
volume mount/unmount (and attach/detach, if attach/detach controller
is not enabled).

This eliminates the race conditions between the pod creation loop
and the orphaned volumes loops. It also removes the unmount/detach
from the `syncPod()` path so volume clean up never blocks the
`syncPod` loop.

Saad Ali 9dbe943491 Attach/Detach Controller Kubelet Changes 
This PR contains Kubelet changes to enable attach/detach controller control.
* It introduces a new "enable-controller-attach-detach" kubelet flag to
  enable control by controller. Default enabled.
* It removes all references "SafeToDetach" annoation from controller.
* It adds the new VolumesInUse field to the Node Status API object.
* It modifies the controller to use VolumesInUse instead of SafeToDetach
  annotation to gate detachment.
* There is a bug in node-problem-detector that causes VolumesInUse to
  get reset every 30 seconds. Issue https://github.com/kubernetes/node-problem-detector/issues/9
  opened to fix that.

saadali 92500a20d7 Attach detach controller business logic added 
Split controller cache into actual and desired state of world.
Controller will only operate on volumes scheduled to nodes that
have the "volumes.kubernetes.io/controller-managed-attach" annotation.

Jan Safranek 0ee9160f88 volume recycler: Don't start a new recycler pod if one already exists. 
Recycling is a long duration process and when the recycler controller is
restarted in the meantime, it should not start a new recycler pod if there is
one already running.

This means that the recycler pod must have deterministic name based on name
of the recycled PV, we then get name conflicts when creating the pod.

Two things need to be changed:
- recycler controller and recycler plugins must pass the PV.Name to place,
  where the pod is created.

- create recycler pod with deterministic name and check "already exists" error.

When at it, remove useless 'resourceVersion' argument and make log messages
starting with lowercase.

Jan Safranek a304e3478d Hot-fix admission of volumes that are being provisioned. 
This is a first-aid bandage to let admission controller ignore persistent
volumes that are being provisioned right now and thus may not exist in
external cloud infrastructure yet.

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.
