code-generator: add NewFilteredSharedInformerFactory function
**What this PR does / why we need it**:
Adds a `namespace` option to the SharedInformerFactory constructor. This is useful when building controllers that may need to scope themselves to a namespace due to RBAC constraints.
Workarounds for this involve losing type safety if a user wants to use it for core APIs as well as a SharedInformerFactory type interface, as we have to deal with plain SharedIndexInformers (example here: https://github.com/jetstack-experimental/cert-manager/blob/master/pkg/util/kube/factory.go)
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #
Fixes https://github.com/kubernetes/code-generator/issues/9
**Special notes for your reviewer**:
This will require updating all uses of SharedInformerFactory throughout the codebase. I'm going to follow up with later commits in this PR with these changes, but wanted to get this here to get some feedback on the way it's implemented.
**Release note**:

certificate manager: reduce max backoff from 128s to 32s
For TLS bootstrapping in bootkube we run a kubelet with a control plane run through static pods. That static control plane has an API server and controller manager that approve the kubelet's CSR.
Since the kubelet has to wait for the static control plane to come up to be approved, we hit this backoff every time and it actually adds a notable overhead to startup times.
https://github.com/kubernetes-incubator/bootkube/pull/663
If this choice is somewhat arbitrary, I'd like to see it lowered for 1.9.

client-go/tools/cache: fix possible deadlock when stopping a reflector
While getting Connection-Refused error, a reflector was retrying without stopping when the stopCh is closed.
The flaking TestCRD #54095 sometimes shows a deadlock in reflectors that should be shutdown, called from the storage cacher. So possibly this is related.

vendor update: github.com/golang/protobuf
When I'm working on PR: https://github.com/kubernetes/kubernetes/pull/54782, I met a problem here: https://github.com/golang/protobuf/issues/372, which I think we need to update our vendor of protobuf
and I ask Dr. Stefan for suggestion, here is our coversation
shiywang [5:09 PM]
hi, Dr. Stefan i'm sorry to bother, I have a simple question, I was working on a pr which need to use protobuf custom field, and I run into this problem here: https://github.com/golang/protobuf/issues/372 which I think is due to our codebase's protobuf vendor is too old `vendor/github.com/golang/protobuf`, do you think I can update that vendor to lastest one ? also I noticed there's also an extend package called `vendor/github.com/gogo/protobuf/proto` what's the releationship between those two ? which one should I update ?

hi
[5:11]
don't know much about the proto internals either, @claytonc is probably the only one
[5:12]
create a vendor/github.com/golang/protobuf bump PR and assign it to him

Upgrade Azure SDK to v11.1.1
**What this PR does / why we need it**: This fixes various Azure SDK bugs per the Azure SDK for Go changelogs:
* Fixed bug in which blob types were unmarshaled incorrectly
* Fixed various package names
* Miscellaneous unspecified storage bug fixes
This is also a prerequisite for a bug fix for running out of firewall rules when exposing large numbers of services from an Azure cluster.
**Which issue(s) this PR fixes**: None
**Special notes for your reviewer**:
1. I inadvertently committed a compatibility fix along with the dependency upgrade (which the guidelines say should have been two separate commits). The offending file is `pkg/cloudprovider/providers/azure.go`.
2. We require an urgent bug fix for the firewall rules limit so it would be great if we could get this agreed quickly. I have struggled with the dependency upgrade process a bit so if it looks wrong, please let me know as soon as you can! Thanks!
**Release note**:
```release-note
Upgraded Azure SDK to v11.1.1.

Fix Incorrect Scale Subresources and HPA e2e ScaleTargetRefs
The HPA e2es failed to actually set `apiVersion` on the created HPAs, which previous was ignored. Since the polymorphic scale client was merged, this behavior is no longer tolerated (it was never correct to begin with, but it accidentally worked).
Additionally, the `apps` resources have their own version of scale. Until `apps/v1beta1` and `apps/v1beta2` go away, we need to support those versions in the scale client.
Together, these broke some of the HPA e2es.
Fixes#54574

Workloads V1
**What this PR does / why we need it**: This PR promotes the Deployment, ReplicaSet, and DaemonSet StatefulSet, ControllerRevision kinds to the apps/v1 group version.
https://github.com/kubernetes/features/issues/353
**Special notes for your reviewer**:
There will be at least two followups to this PR. The first to add a scale sub-resource when the correct location is resolved, and the second to deal with Conditions in the workloads API.
While it would have been preferable to move the kinds individually providing a lesser burden on reviewers, this proved impracticable due to the intricacies of version resolution in kubectl for objects of the different kinds in the same group.
```release-note
DaemonSet, Deployment, ReplicaSet, and StatefulSet have been promoted to GA and are available in the apps/v1 group version.

Polymorphic Scale Client
This PR introduces a polymorphic scale client based on discovery information that's able to scale scalable resources in arbitrary group-versions, as long as they present the scale subresource in their discovery information.
Currently, it supports `extensions/v1beta1.Scale` and `autoscaling/v1.Scale`, but supporting other versions of scale if/when we produce them should be fairly trivial.
It also updates the HPA to use this client, meaning the HPA will now work on any scalable resource, not just things in the `extensions/v1beta1` API group.
**Release note**:
```release-note
Introduces a polymorphic scale client, allowing HorizontalPodAutoscalers to properly function on scalable resources in any API group.

Use GetByKey() in typeLister_NonNamespacedGet
The Get() function of non-namespace lister passes a temporary object to
indexer.Get() in order to fetch the actual object from the indexer. This
may cause Go to allocate the temporary object on the heap instead of the
stack, as it is passed into interfaces. For non-namespaced objects,
Get(&Type{ObjectMeta: v1.ObjectMeta{Name: name}}) should be equivalent
to GetByKey(name).
This could be the root cause of excessive allocations, e.g. in tests
clusterRoleLister.Get() has trigger 4 billion allocations. See
openshift/origin#16954
