Node Conformance Test: Statically link etcd
For #30122, #30174.
This PR is part of our roadmap to package node conformance test.
It statically linked etcd into the node e2e framework. In the future all e2e services will be linked in, and print log into the same log file `services.log`.

Nodecontroller doesn't flip readiness on pods if kubeletVersion < 1.2.0
Older versions of the kubelet didn't know how to reconcile pod.Status, so the nodecontroller would mark pods NotReady on netsplit, and if the partition recovered in < 5m, the pods would never get marked Ready resulting in NotReady endpoints indefinitely (till kubelet restart/pod recreate etc).

Provide absolute path to cross build image VERSION file.
This allows invoking builds from non-root directories. This in turn allows invoking federation `make` from the `federation/` directory.
This implements the proposal in:
docs/proposals/secret-configmap-downwarapi-file-mode.md
Fixes: #28317.
The mounttest image is updated so it returns the permissions of the linked file
and not the symlink itself.

Display one or many resources.
Possible resource types include (case insensitive): pods (aka 'po'), services (aka 'svc'), deployments (aka 'deploy'),
replicasets (aka 'rs'), replicationcontrollers (aka 'rc'), nodes (aka 'no'), events (aka 'ev'), limitranges (aka 'limits'),
persistentvolumes (aka 'pv'), persistentvolumeclaims (aka 'pvc'), resourcequotas (aka 'quota'), namespaces (aka 'ns'),
serviceaccounts (aka 'sa'), ingresses (aka 'ing'), horizontalpodautoscalers (aka 'hpa'), daemonsets (aka 'ds'), configmaps (aka 'cm'),
componentstatuses (aka 'cs), endpoints (aka 'ep'), petsets (alpha feature, may be unstable) and secrets.
This command will hide resources that have completed. For instance, pods that are in the Succeeded or Failed phases.
You can see the full results for any resource by providing the '--show-all' flag.
By specifying the output as 'template' and providing a Go template as the value
of the --template flag, you can filter the attributes of the fetched resource(s).

pkg/storage: remove Codec() from interface
What?
Removes Codec() from storage.Interface.
Why?
- storage interface doesn't need to expose Codec().
- Codec() isn't used anywhere.
