Add image pulling node e2e

Fixes #27007.
Based on #27309, will rebase after #27309 gets merged.

This PR added all tests mentioned in #27007:
* Pull an image from invalid registry;
* Pull an invalid image from gcr;
* Pull an image from gcr;
* Pull an image from docker hub;
* Pull an image needs auth with/without secrets.

For the imagePullSecrets test, I created a new gcloud project "authenticated-image-pulling", and the service account in the code only has "Storage Object Viewer" permission.

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.

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: https://github.com/kubernetes/kubernetes/blob/6a388d4a0d9e7fc2549ab89c97bf29ce53982e39/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.
