The ephemeral containers API changed in 1.22. As a result, kubectl
debug (currently) cannot create ephemeral containers in clusters prior
to 1.22.
This change causes kubectl to retry the request using the old API when
it receives a specific error message from the server.

Add a warning message to `kubectl debug` when using the `--target`
option as many runtimes don't support it yet.

* Use deep copies in `PrepareForUpdate()`
* Preserve select metadata from new pod
* Use patch to add ephemeral container `kubectl debug`
* Distinguish between pod vs /ephemeralcontainers NotFound

This changes the `/ephemeralcontainers` subresource of `/pods` to use
the `Pod` kind rather than `EphemeralContainers`.
When designing this API initially it seemed preferable to create a new
kind containing only the pod's ephemeral containers, similar to how
binding and scaling work.
It later became clear that this made admission control more difficult
because the controller wouldn't be presented with the entire Pod, so we
updated this to operate on the entire Pod, similar to how `/status`
works.

Fix containerNameToRef func to get init containers and ephemeral containers properly.
Set EphemeralContainers in generatePodCopyWithDebugContainer func to nil which means
dropping ephemeral containers from a copy of pod so that it can be created successfully,
otherwise it is rejected by the API server.

When called with a node target, `kubectl debug` will create a run-once
pod in the target node's namespaces.

This first version of `kubectl alpha debug` is an import of the existing
kubectl-debug plugin, which supports adding ephemeral containers to
running pods. This attempts to follow patterns used by other kubectl
commands such as run, exec and scale.
