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.
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.

add information for subresource kind determination
xref https://github.com/kubernetes/kubernetes/issues/38810https://github.com/kubernetes/kubernetes/issues/38756
Polymorphic subresources usually have different groupVersions for their discovery kinds than their "native" groupVersions. Even though the APIResourceList shows the kind properly, it does not reflect the group or version of that kind, which makes it impossible to unambiguously determine if the subresource matches you and it is impossible to determine how to serialize your data. See HPA controller.
This adds an optional Group and Version to the discovery doc, which can be used to communicate the "native" groupversion of an endpoint. Doing this does not preclude fancier contenttype negotiation in the future and doesn't prevent future expansion from indicating equivalent types, but it does make it possible to solve the problem we have today or polymorphic categorization.
@kubernetes/sig-api-machinery-misc @smarterclayton
@cheftako since @lavalamp is out.
```release-note
Adds optional group and version information to the discovery interface, so that if an endpoint uses non-default values, the proper value of "kind" can be determined. Scale is a common example.

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.

- [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.

update scheduler to return structured errors instead of process exit
The scheduler Run method returns an error that is properly handled at higher levels. Instead of existing the process, we should return the error and handle it at higher level logic to allow testing of error conditions and composition of commands. The changes are relatively minor.
