Disable default paging in list watches
For 1.8 this will be off by default. In 1.9 it will be on by default.
Add tests and rename some fields to use the `chunking` terminology.
Note that the pager may be used for other things besides chunking.
Follow on to #48921, we left the field on to get some exercise in the normal code paths, but needs to be disabled for 1.8.

Move autoscaling/v2 from alpha1 to beta1
This graduates autoscaling/v2alpha1 to autoscaling/v2beta1. The move is more-or-less just a straightforward rename.
Part of kubernetes/features#117

v2 of the autoscaling API group, including improvements to the HorizontalPodAutoscaler, has moved from alpha1 to beta1.

Graduate metrics/v1alpha1 to v1beta1
This introduces v1beta1 of the resource metrics API, previously in alpha.
The v1alpha1 version remains for compatibility with the Heapster legacy version
of the resource metrics API, which is compatible with the v1alpha1 version. It also
renames the v1beta1 version to `resource-metrics.metrics.k8s.io`.
The HPA controller's REST clients (but not the legacy client) have been migrated as well.
Part of kubernetes/features#118.
```release-note
Migrate the metrics/v1alpha1 API to metrics/v1beta1. The HorizontalPodAutoscaler
controller REST client now uses that version. For v1beta1, the API is now known as
resource-metrics.metrics.k8s.io.

Enable batch/v1beta1.CronJobs by default
This PR re-applies the cronjobs->beta back (https://github.com/kubernetes/kubernetes/pull/51720) with the fix from @shyamjvs.
Fixes#51692
@apelisse @dchen1107 @smarterclayton ptal
@janetkuo @erictune fyi
Job failure policy integration in JobController. From the
JobSpec.BackoffLimit the JobController will define the backoff
duration between Job retry.
It use the ```workqueue.RateLimitingInterface``` to store the number of
"retry" as "requeue" and the default Job backoff initial duration is set
during the initialization of the ```workqueue.RateLimiter.
Since the number of retry for each job is store in a local structure
"JobController.queue" if the JobController restarts the number of retries
will be lost and the backoff duration will be reset to 0.
Add e2e test for Job backoff failure policy

Slow-start batch pod creation of rs, rc, ds, jobs
Prevent too-large replicas from generating enormous numbers
of events by creating only a few pods at a time, then increasing
the batch size when pod creations succeed. Stop creating batches
of pods when any pod creation errors are encountered.
Todo:
- [x] Add automated tests
- [x] Test ds

Add IPAM controller for synchronizing node pod CIDR range allocations between the cluster and the cloud (alpha feature)
```release-note
IPAM controller unifies handling of node pod CIDR range allocation.
It is intended to supersede the logic that is currently in range_allocator
and cloud_cidr_allocator. (ALPHA FEATURE)
Note: for this change, the other allocators still exist and are the default.
It supports two modes:
* CIDR range allocations done within the cluster that are then propagated out to the cloud provider.
* Cloud provider managed IPAM that is then reflected into the cluster.

Add a feature gate in the apiserver to control whether paging can be
used. Add controls to the storage factory that allow it to be disabled
per resource. Use a JSON encoded continuation token that can be
versioned. Create a 410 error if the continuation token is expired.
Adds GetContinue() to ListMeta.

Ensure that DaemonSet respects termination
**What this PR does / why we need it**:
#43077 correctly prevents the DaemonSet controller from adopting deleted Pods, but, as pointed out in #50477, the controller now has no sensitivity to the termination lifecycle (i.e TerminationGracePeriodSeconds) of the Pods it creates. This PR attempts to balance the two. DaemonSet controller will now consider deleted Pods owned by a DaemonSet during creation, but it will not consider deleted Pods as targets for adoption.
fixes#50477
```release-note
#43077 introduced a condition where DaemonSet controller did not respect the TerminationGracePeriodSeconds of the Pods it created. This is now corrected.

Add a persistent volume label controller to the cloud-controller-manager
Part of https://github.com/kubernetes/features/issues/88
Outstanding concerns needing input:
- [x] Why 5 threads for controller processing?
- [x] Remove direct linkage to aws/gce cloud providers [#51629]
- [x] Modify shared informers to allow added event handlers ability to include uninitialized objects/using unshared informer #48893
- [x] Use cache.MetaNamespaceKeyFunc in event handler?
I'm willing to work on addressing the removal of the direct linkage to aws/gce after this PR gets in.
