GCE - Refactor API for firewall and backend service creation
**What this PR does / why we need it**:
- Currently, firewall creation function actually instantiates the firewall object; this is inconsistent with the rest of GCE api calls. The API normally gets passed in an existing object.
- Necessary information for firewall creation, (`computeHostTags`,`nodeTags`,`networkURL`,`subnetworkURL`,`region`) were private to within the package. These now have public getters.
- Consumers might need to know whether the cluster is running on a cross-project network. A new `OnXPN` func will make that information available.
- Backend services for regions have been added. Global ones have been renamed to specify global.
- NamedPort management of instance groups has been changed from an `AddPortsToInstanceGroup` func (and missing complementary `Remove...`) to a single, simple `SetNamedPortsOfInstanceGroup`
- Addressed nitpick review comments of #45524
ILB needs the regional backend services and firewall refactor. The ingress controller needs the new `OnXPN` func to decide whether to create a firewall.

NONE

Remove deletecollection support from namespace object
Namespace storage accidentally picked up deletecollection support from embedding the generic store. If invoked, it skips the custom namespace `Delete()` storage method that enforces finalization, and skips the namespace lifecycle admission plugin that protects immortal namespaces from deletion.
Given the data integrity implications of skipping namespace finalization, I'd backport this as far as we're releasing patch releases.
```release-note
The namespace API object no longer supports the deletecollection operation.
```
Previous behavior was to write to stderr (thanks to the fallback system
in the Cobra library), which made it difficult to grep for flags.
For example:
kubectl options | grep recursive

Protobuf generation for k8s.io/metrics
This PR introduces protobuf generation for k8s.io/metrics. Doing so required:
- fixing a bug in `go-to-protobuf` causing the `cast{key,value,type}` values to not be quoted when coming from struct tags (and not auto-injection by `go-to-protobuf` itself).
- Making sure the proto IDL in k8s.io/client-go had a package name of `k8s.io.client_go.xyz` and not `k8s.io.kubernetes.xyz`.
Additionally, I updated `go-to-protobuf` to skip functions and non-public types when composing the import list, which cuts down on the more bizarre imports in the IDL (like importing the sample API package in every IDL file because it contained `addToScheme`, like every other API package).
We use `castvalue` to force gogo-proto to realize that it should consider the value of the map which underlies `ResourceList` when calculating which imports need to be named. Otherwise, it ignores the value's type, leading to compilation errors when it later can't find an import it assumed existed. We accidentally didn't hit this in `k8s.io/kubernetes/pkg/api/v1` since another field coincidentally happens to directly use `resource.Quantity` (the value type of `ResourceList`).
**Release note**:
```release-note
NONE
```
This commit regenerates the protobuf as per the recent generation
changes (removing erroneous imports, adding k8s.io/metrics), and
syncs the changes to client-go (which also ensures that client-go
protobuf IDL has the correct package names).

Support sandbox images from private registries
**What this PR does / why we need it**:
The --pod-infra-container-image parameter allows the user to specify
an arbitrary image to be used as the pod infra container (AKA
sandbox), an internal piece of the dockershim implementation of the
Container Runtime Interface.
The dockershim does not have access to any of the pod-level image pull
credentials configuration, so if the user specifies an image from a
private registry, the image pull will fail.
This change allows the dockershim to read local docker configuration
(e.g. /root/.docker/config.json) and use it when pulling the pod infra
container image.
**Which issue this PR fixes**: fixes#45738
**Special notes for your reviewer**:
The changes to fake_client for writing local config files deserve some
attention.
**Release note**:
```release-note
NONE

Make GCE load-balancers create health checks for nodes
From #14661. Proposal on kubernetes/community#552. Fixes#46313.
Bullet points:
- Create nodes health check and firewall (for health checking) for non-OnlyLocal service.
- Create local traffic health check and firewall (for health checking) for OnlyLocal service.
- Version skew:
- Don't create nodes health check if any nodes has version < 1.7.0.
- Don't backfill nodes health check on existing LBs unless users explicitly trigger it.
**Release note**:
```release-note
GCE Cloud Provider: New created LoadBalancer type Service now have health checks for nodes by default.
An existing LoadBalancer will have health check attached to it when:
- Change Service.Spec.Type from LoadBalancer to others and flip it back.
- Any effective change on Service.Spec.ExternalTrafficPolicy.
