kubelet/rkt - treat pod container as the infra - only network stats
As no "container name" annotation was being applied to the pod as a whole, the rkt pod container didn't have a container name label. This means that in stat/summary it came up as a nameless container that belonged to the pod.
this was problematic as it caused double counting of container stats.
this adds a container name annotation to the pod level which will be overridden during label creation by annotations of the same name at the container level for the containers themselves.
stats/summary will do the right thing as it will treat it the same as the infra container, just get network stats from it.
Suppress #26759

federation: fix dns provider initialization issues
This PR is based on the integration test with Google DNS API. This is the first time of full integration test.
So multiple issues was found and I combined all of them in this single PR
1. add dns provider initialization and add ensureDns call when removing federation service.
2. add new flags federation-name and zone-name to controller manager, both are used as part of the dns record name
3. fix assertion failure at rrsets.go#L61, which will cause panic
4. change getFederationDNSZoneName to get zoneName from config instead of hard code
5. change logic of ensureDnsRrsets, only add new dns record when endpointReachable(set to true when ready address is catched) is true
6. fix bug in processEndpointUpdate, only call ensuredns when ready address is caught
7. change behavior of syncService, there is cases that endpoint is created before ingress IP assignment, so before there is defect for this case, ensureDns was not called when service being updated, so if Ingress IP is assigned after endpoint ready address is caught, the corresponding A records can not be created
8. add a checking before update federation service
@nikhiljindal , can you help to add 1.3 milestone when @quinton-hoole is on leave?
Thanks.

Updating federation up scripts to work in non e2e setup
Ref: https://github.com/kubernetes/kubernetes.github.io/pull/656
Updating the federation up scripts so that they work as per steps in https://github.com/kubernetes/kubernetes.github.io/pull/656.
Changes are:
* Updating the default namespace to be "federation" instead of "federation-e2e"
* Updated the kubeconfig context to be named "federation-cluster" instead of "federated-context"
* Fixing federation-up so that FEDERATION_IMAGE_TAG is set even when federation-up is run without running `e2e.go --up`. e2e-up.sh sets it here: 6a388d4a0d/hack/e2e-internal/e2e-up.sh (L44).
* Adding a "missingkey=zero" option to template parser. Without this, the parser adds `"<no value>"` at the place of an env var that is not set. With this change, it instead replaces it with the corresponding zero value (for ex "" for strings). This is required for the FEDERATION_DNS_PROVIDER_CONFIG env var.

Rbac api group make subject apiversion optional
This fixes the verification for the "apiVerion" field in the RBAC subject and makes it optional. This field isn't used and currently won't pass validation if it's filled.
```yml
kind: ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1alpha1
metadata:
name: admins
subject:
- kind: User
name: admin-user
# apiVersion: "entering anything here will fail validation"
roleRef:
kind: ClusterRole
name: admin
apiVersion: rbac.authorization.k8s.io/v1alpha1

GCI: fix multizone setting in issue #27150
This PR is for fixing the issue. We gradually added more cases of using /etc/gce.conf, but in the config code we did not update the condition of computing env variables. As a result, the muitlzone setting was ignored.
I manually verified that with the fix we can create a multi-zone cluster with master on GCI.

In nsenter_mount.go/isLikelyNotMountPoint function, the returned output
from findmnt command misses the last letter. Modify the code to make sure
that output has the full target path. fix#26421#25056#22911
- replaces probeVolume with scsiHostRescan to scan hot attached disks
- fixes substring match of UUID returned from AttachDisk
- changes DetachDisk to take volumePath argument instead of diskID
- fixes delayed failure at mount rather than attach disk
- removes cloning of virtual disk in AttachDisk
The previous size, of 2KB, in practice always was filled completely by
http server-releated stuff well above the panic itself, and truncated
before anything of real value was printed.
This increases the stack size so that panics are printed in full.

Implement first set of federated service e2e tests.
These tests are untested and there is no guarantee that they work. The ongoing auth problems is blocking these e2es from being tested and upon @quinton-hoole's request I am submitting them now.
Only the last commit here needs review.
Depends on #26953
