Collect ephemeral storage capacity on initialization
**What this PR does / why we need it**:
We have had some node e2e flakes where a pod can be rejected if it requests ephemeral storage. This is because we don't set capacity and allocatable for ephemeral storage on initialization.
This PR causes cAdvisor to do one round of stats collection during initialization, which will allow it to get the disk capacity when it first sets the node status.
It also sets the node to NotReady if capacities have not been initialized yet.
**Special notes for your reviewer**:
**Release note**:

Updated PID pressure node condition

This is the 2nd attempt. The previous was reverted while we figured out
the regional mirrors (oops).
New plan: k8s.gcr.io is a read-only facade that auto-detects your source
region (us, eu, or asia for now) and pulls from the closest. To publish
an image, push k8s-staging.gcr.io and it will be synced to the regionals
automatically (similar to today). For now the staging is an alias to
gcr.io/google_containers (the legacy URL).
When we move off of google-owned projects (working on it), then we just
do a one-time sync, and change the google-internal config, and nobody
outside should notice.
We can, in parallel, change the auto-sync into a manual sync - send a PR
to "promote" something from staging, and a bot activates it. Nice and
visible, easy to keep track of.
Adds support for the following:
1. A node resource to be assigned an IPv6 address.
2. Expands IPv4/v6 address validation checks.
Which issue this PR fixes:
fixes#44848 in combination with PR #45116
Special notes for your reviewer:
Release note:
With this PR, nodes can be assigned an IPv6 address. An IPv4 address is
preferred over an IPv6 address. IP address validation has been expanded
to check for multicast, link-local and unspecified addresses.
When a node IP is set and a cloud provider returns the same address with
several types, on the first address was accepted. With the changes made
in PR #45201, the vSphere cloud provider returned the ExternalIP first,
which led to a node without any InternalIP.
The behaviour is modified to return all the address types for the
specified node IP.
Issue #48760
Centralize Capacity discovery of standard resources in Container manager.
Have storage derive node capacity from container manager.
Move certain cAdvisor interfaces to the cAdvisor package in the process.
This patch fixes a bug in container manager where it was writing to a map without synchronization.

- Wrapping all node statuses from local storage capacity isolation under an alpha feature check. Currently there should not be any storage statuses.
- Replaced all "storage" statuses with "storage.kubernetes.io/scratch". "storage" should never be exposed as a status.
This PR adds the check for local storage request when admitting pods. If
the local storage request exceeds the available resource, pod will be
rejected.

CRI: Add Status into CRI.
For https://github.com/kubernetes/kubernetes/issues/35701.
Fixes https://github.com/kubernetes/kubernetes/issues/35701.
This PR added a `Status` call in CRI, and the `RuntimeStatus` is defined as following:
``` protobuf
message RuntimeCondition {
// Type of runtime condition.
optional string type = 1;
// Status of the condition, one of true/false.
optional bool status = 2;
// Brief reason for the condition's last transition.
optional string reason = 3;
// Human readable message indicating details about last transition.
optional string message = 4;
}
message RuntimeStatus {
// Conditions is an array of current observed runtime conditions.
repeated RuntimeCondition conditions = 1;
}
```
Currently, only `conditions` is included in `RuntimeStatus`, and the definition is almost the same with `NodeCondition` and `PodCondition` in K8s api.
@yujuhong @feiskyer @bprashanth If this makes sense, I'll send a follow up PR to let dockershim return `RuntimeStatus` and let kubelet make use of it.
@yifan-gu @euank Does this make sense to rkt?
