add a delayed queueing option to the workqueue
Adds delayed requeuing to the workqueue so that I requeue an item to be retried at some later time in my controller with a series of backoff rules. It lets me have the best of the retryManager and the work queue de-duping. Tracking failures and backoffs is on the caller
@smarterclayton @pweil- this would help us move to using the informer everywhere and de-duping at that level.

Fixed mounting with containerized kubelet
`NsenterMounter.IsLikelyNotMountPoint()` should return `ErrNotExist` when the
checked directory does not exists - the regular mounted does this and
some volume plugins depend on this behavior.
See for example: https://github.com/kubernetes/kubernetes/blob/master/pkg/volume/aws_ebs/aws_util.go#L72

Implement a streaming serializer for watch
Changeover watch to use streaming serialization. Properly version the
watch objects. Implement simple framing for JSON and Protobuf (but not
YAML).

Preserve int data when unmarshaling
There are several places we use `json.Unmarshal` into an unstructured map (StrategicMergePatch, UnstructuredJSONScheme, many others).
In this scenario, the json package converts all numbers to float64. This exposes many of the int64 fields in our API types to corruption when the unstructured map is marshalled back to json.
A simple example is a pod with an `"activeDeadlineSeconds": 1000000`. Trying to use `kubectl label`, `annotate`, `patch`, etc results in that int64 being converted to a float64, submitted to the server, and the server rejecting it with an error about "cannot unmarshal number 1e+6 into Go value of type int64"
The json package provides a way to defer conversion of numbers (`json.Decoder#UseNumber`), but does not actually do conversions to int or float. This PR makes use of that feature, and post-processes the unmarshalled map to convert json.Number objects to either int64 or float64 values

Additional go vet fixes
Mostly:
- pass lock by value
- bad syntax for struct tag value
- example functions not formatted properly

Move typed clients into clientset folder
Move typed clients from `pkg/client/typed/` to `pkg/client/clientset_generated/${clientset_name}/typed`.
The first commit changes the client-gen, the last commit updates the doc, other commits are just moving things around.

Use correct home directory on Windows
As of now the `kubectl` config mechanism that saves/loads `~/.kube/config` is broken on Windows, saving the config file in the *current* directory instead of the user's *home* dir. This happens because most Windows don't respect the `HOME` environment variable.
This PR changes the config file loading mechanism to use the recommended way to detect the user home on Windows (`HOMEDRIVE`+`HOMEPATH` or `USERPROFILE`), and adds a migration for users that might be currently relying on existing config files.

Refactor streaming code to support interop testing
Refactor exec/attach/port forward client and server code to better
support interop testing of different client and server subprotocol
versions.
Fixes#16119
os/signal.Stop() does not actually close the channel, which means
the channel is blocked. Not serious because we don't use interrupt
protection on the server, just the CLI (which can afford 1 leaked
goroutine).
Kubelet was not able to mount volumes when running inside a container and
using nsenter mounter,
NsenterMounter.IsLikelyNotMountPoint() should return ErrNotExist when the
checked directory does not exists as the regular mounted does this and
some volume plugins depend on this behavior.
Currently attach and the editor do not share the same logic for saving
and restoring the terminal, and are not suitable for nesting (when the
caller wants to create something, attach, and then delete something when
the attach is over). This commit moves the interrupt protection logic
to a util package and supports nesting interrupt handlers.
