- CRI flows the websocket ports as query params
- Do not validate ports since the protocol is unknown
SPDY flows the ports as headers and websockets uses query params
- Only flow query params if there is at least one port query param

Allow multiple port forwarding ports
- Make it easy to determine which port is tied to which channel
- odd channels are for data
- even channels are for errors
- allow comma separated ports to specify multiple ports

Check if error is Status in result.Stream()
Fix#38774
This adds the same functionality to `.Stream()` that was added to `.Error()`, `.Into()`, and `.Get()` in ce187f9c6a to try decoding the body as a Status.
This broke `.Stream()` because the decoding of the body as `Status` was removed from `transformResponse` in ce187f9c6a (diff-de85e3effc36b7bbe3fb9eae6c833cf3L933)

Add optional per-request context to restclient
**What this PR does / why we need it**: It adds per-request contexts to restclient's API, and uses them to add timeouts to all proxy calls in the e2e tests. An entire e2e shouldn't hang for hours on a single API call.
**Which issue this PR fixes**: #38305
**Special notes for your reviewer**:
This adds a feature to the low-level rest client request feature that is entirely optional. It doesn't affect any requests that don't use it. The api of the generated clients does not change, and they currently don't take advantage of this.
I intend to patch this in to 1.5 as a mostly test only change since it's not going to affect any controller, generated client, or user of the generated client.

replace global registry in apimachinery with global registry in k8s.io/kubernetes
We'd like to remove all globals, but our immediate problem is that a shared registry between k8s.io/kubernetes and k8s.io/client-go doesn't work. Since client-go makes a copy, we can actually keep a global registry with other globals in pkg/api for now.

Related downstream PR: https://github.com/openshift/origin/pull/12062 (example of use-case for this patch)
**Release note**:
```release-note
release-note-none
```
This patch adds a package `pkg/client/unversioned/clientcmd/util` and
defines a `ParseTimeout` helper function for parsing time from a
user-defined string. This allows code re-use in other packages that
require the creation of a new restclient (and therefore must set the
`--global-timeout` flag value manually).

Rename "release_1_5" clientset to just "clientset"
We used to keep multiple releases in the main repo. Now that [client-go](https://github.com/kubernetes/client-go) does the versioning, there is no need to keep releases in the main repo. This PR renames the "release_1_5" clientset to just "clientset", clientset development will be done in this directory.

fix connection upgrades through kuberentes-discovery
The initial upgrade through the proxy doesn't use the passed transport to handle the communication to the remote side. Since we need auth proxy headers, this broke the upgrade for exec.
This sets those headers once if its an upgrade request (the transport stomps them if called anyway, so it won't shadow.).
@sttts I think this is the last required piece. Then we start wiring in for e2e.

Fake clientset propagates namespace to objects on create/update
**What this PR does / why we need it**:
Unlike the real Clientset, the fake Clientset requires creates and updates of namespaced objects to have the namespace specified in the target runtime object metadata. This difference forces API clients using the fake Clientset for test to propagate the namespaces to the runtime objects in the production code. This propagation is unnecessary and should be handled by the fake implementation.

Logging request / response body should not allocate
Putting string(data) in the critical path causes an allocation which can
be very large, and happens regardless of whether logging is enabled.
Also, use the more sophisticated logging of body output that avoids
causing quoting of JSON output (current behavior is "{\"key\":...}" and
should be {"key":...} for readability).

Limit unbound label cardinality on request errors
This converts all request errors to the string `<error>` instead of
passing the full error string. Error strings can have arbitrary values
and thus have a cardinality that is not suitable for a metric
use case.
Inspecting individual errors is a logging use case which can be handled separately by registering a client error handler.

we search all defaultGroupVersion as opposed to just one when no mapping was found for provided versions.

Read all resources for finalization and gc, not just preferred
Fixes#31481.
Currently when starting namespace controller or garbage collector we only gather preferred version resources, which in case of multiple versions (you guessed it `batch/v2alpha1.CronJobs` again) isn't sufficient. This PR adds additional method which actually retrieves all resources from all versions and works on them.

Fix strategic patch for list of primitive type with merge sementic
Fix strategic patch for list of primitive type when the patch strategy is `merge`.
Before: we cannot replace or delete an item in a list of primitive, e.g. string, when the patch strategy is `merge`. It will always append new items to the list.
This patch will generate a map to update the list of primitive type.

Expand documentation and TODOs in a few packages
I was reading through unfamiliar code and mostly added TODOs and expanded and clarified documentations.
There are a couple of things that are real code changes:
- Removed some unused constants
- Changed `workqueue.Parallize` to clamp the number of worker goroutines to the number of items to be processed.
- Added another unit test to `workqueue.queue`. I thought I found a bug (I was wrong) and wrote a unit test to isolate. I figure the extra test is worth keeping.
