30e6509a72 staging: extract CRI streaming modules with client-go compatibility
Extract streaming code into dedicated staging modules while keeping stable
compatibility APIs for external client-go consumers.

This commit:
- adds `k8s.io/cri-streaming` for CRI exec/attach/portforward server code
- adds `k8s.io/streaming` as the canonical home for shared transport
  primitives (`httpstream`, `spdy`, `wsstream`, runtime helpers)
- switches in-tree transport consumers to `k8s.io/streaming`
- removes in-tree kubelet CRI streaming package
- preserves NO_PROXY/no_proxy CIDR handling in extracted SPDY proxier logic
- adds deprecated `k8s.io/apimachinery/pkg/util/httpstream` compatibility
  wrappers (`httpstream`, `spdy`, `wsstream`) backed by `k8s.io/streaming`
- restores exported client-go SPDY/portforward API signatures to
  apimachinery `httpstream` types for downstream compatibility
- adds streaming-native client-go adapters/constructors so in-tree callers
  can use `k8s.io/streaming` without changing external compatibility APIs
- deduplicates SPDY-over-websocket dial negotiation shared by compat and
  streaming tunneling dialers
- logs dropped unknown stream types in `RemoveStreams` adapter fallbacks to
  improve compatibility-path debuggability
- adds integration coverage for the streaming-upgrader-to-client-go-compat
  adapter path against a real cri-streaming exec endpoint
- clarifies kubectl streaming import aliasing to avoid `httpstream` package
  ambiguity
- updates tests, import restrictions, publishing metadata, and vendor/module
  metadata for the new staging modules

cd245d2e22 Support completion for the <type>/<name> form
This commit teaches the shell completion logic how to handle the
<type>/<name> form for resource specification.

It also teaches the 'exec' command how to complete its '--container/-c'
flag using container names.

Also, for commands that work on pods, kubectl will now also suggest
completion choices of the form <type>/<name> for resource types that
contain pods (see below for more details).

The following commands can now have completion of the <type>/<name>
form. Commands that accept any resource type:

annotate
apply edit-last-applied
apply view-last-applied
delete
describe
edit
get
label
patch

Commands that accept a subset of resource types:

autoscale
expose
rollout history
rollout pause
rollout restart
rollout resume
rollout status
rollout undo
scale
taint

Commands that apply to resource types that contain pods:

attach
exec
logs
port-foward

For these last four commands, the possible resource types are now
included in the completion choices.  For example:
    kubectl exec d<TAB>
will suggest
    daemonsets/   deployments/

a0af655b7a kubectl default container behavior

56434236a4 kubectl: Inline the containers for the user in attach/exec
The behavior of the container defaulting in attach/exec is inconsistent
and should be unified. As a user, when we default the vast majority of
pods will have a small number of containers and so printing the container
names inline (as kubectl logs did) is more appropriate. The debug message
we printed about using describe was already longer than 99% of all pod
container names, so we were wasting user time.

Unify container selection for exec and attach to be consistent with old
behavior. Properly handle the --quiet flag (should not print in that case)
for both commands. Remove EnableCmdSuggestion and the machinery it needs.

The message now prints:

> Defaulted container "etcdctl" out of: etcdctl, etcd, etcd-metrics, etcd-ensure-env-vars (init), etcd-resources-copy (init)
