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.

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.

CRI: add methods for container stats
**What this PR does / why we need it**:
Define methods in CRI to get container stats.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*:
Part of https://github.com/kubernetes/features/issues/290; addresses #27097
**Special notes for your reviewer**:
This PR defines the *minimum required* container metrics for the existing components to function, loosely based on the previous discussion on [core metrics](https://github.com/kubernetes/community/blob/master/contributors/design-proposals/core-metrics-pipeline.md) as well as the existing cadvisor/summary APIs.
Two new RPC calls are added to the RuntimeService: `ContainerStats` and `ListContainerStats`. The former retrieves stats for a given container, while the latter gets stats for all containers in one call.
The stats gathering time of each subsystem can vary substantially (e.g., cpu vs. disk), so even though the on-demand model preferred due to its simplicity, we’d rather give the container runtime more flexibility to determine the collection frequency for each subsystem*. As a trade-off, each piece of stats for the subsystem must contain a timestamp to let kubelet know how fresh/recent the stats are. In the future, we should also recommend a guideline for how recent the stats should be in order to ensure the reliability (e.g., eviction) and the responsiveness (e.g., autoscaling) of the kubernetes cluster.
The next step is to plumb this through kubelet so that kubelet can choose consume container stats from CRI or cadvisor.
**Alternatively, we can add calls to get stats of individual subsystems. However, kubelet does not have the complete knowledge of the runtime environment, so this would only lead to unnecessary complexity in kubelet.*
**Release note**:
```release-note
Augment CRI to support retrieving container stats from the runtime.
```

kubelet was sending negative allocatable values
**What this PR does / why we need it**:
if you set reservations > node capacity, the node sent negative values for allocatable values on create. setting negative values on update is rejected.
**Which issue this PR fixes**
xref https://bugzilla.redhat.com/show_bug.cgi?id=1455420
**Special notes for your reviewer**:
at this time, the node is allowed to set status on create. without this change, a node was being registered with negative allocatable values. i think we need to revisit letting node set status on create, and i will send a separate pr to debate the merits of that point.
```release-note
Prevent kubelet from setting allocatable < 0 for a resource upon initial creation.

Node status updater now deletes the node entry in attach updates...
… when node is missing in NodeInformer cache.
- Added RemoveNodeFromAttachUpdates as part of node status updater operations.
**What this PR does / why we need it**: Fixes issue of unnecessary node status updates when node is deleted.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes#42438
**Special notes for your reviewer**: Unit tested added, but a more comprehensive test involving the attach detach controller requires certain testing functionality that is currently absent, and will require larger effort. Will be added at a later time.
There is an edge case caused by the following steps:
1) A node is deleted and restarted. The node exists, but is not yet recognized by Kubernetes.
2) A pod requiring a volume attach with nodeName specifically set to this node.
This would make the pod stuck in ContainerCreating state. This is low-pri since it's a specific edge case that can be avoided.

```release-note
NONE

Support TCP type runtime endpoint for kubelet
**What this PR does / why we need it**:
Currently the grpc server for kubelet and dockershim has a hardcoded endpoint: unix socket '/var/run/dockershim.sock', which is not applicable on non-unix OS.
This PR is to support TCP endpoint type besides unix socket.
**Which issue this PR fixes**
This is a first attempt to address issue https://github.com/kubernetes/kubernetes/issues/45927
**Special notes for your reviewer**:
Before this change, running on Windows node results in:
```
Container Manager is unsupported in this build
```
After adding the cm stub, error becomes:
```
listen unix /var/run/dockershim.sock: socket: An address incompatible with the requested protocol was used.
```
This PR is to fix those two issues.
After this change, still meets 'seccomp' related issue when running on Windows node, needs more updates later.
**Release note**:
