- Register the `openapi-gen` tag in all `doc.go` files where the pkg contains _external_ types.
- Add the `groupName` tag where missing
- Fix cases where `addKnownTypes` was registered twice in the `SchemeBuilder`
- Add `Readme` and `OWNERS` files to `Godeps` directories if missing.

Remove e2e-image-puller
**What this PR does / why we need it**:
A long time ago, We added the image prepulling as a workaround due to
the overwhelming amount of flake caused by pulling during the tests.
This functionality has been broken for a while now when we switched to a
COS image where mounting `docker` binary into `busybox` stopped working.
So we just have dead code we should clean up.

Fixes using externally managed certs for kubeadm
**What this PR does / why we need it**:
The certificates overhaul caused a regression when using external certificates. This fixes that issue so external CAs no longer require a key if all certificates exist.
Walk the certificate tree, at each step checking for a CACert.
If the CACert is found, try to use it to generate certificates.
Otherwise, generate a new CA cert.

Change plugin watcher registration mechanism
**Which issue(s) this PR fixes**: #64637
**Notes For Reviewers**:
The current API the plugin watcher exposes to kubelet is the following:
```golang
type RegisterCallbackFn func(pluginName string, endpoint string,
versions []string, socketPath string) (error, chan bool)
```
The callback channel is here to signal the plugin watcher consumer when the plugin watcher API has notified the plugin of it's successful registration.
In other words the current lifecycle of a plugin is the following:
```
(pluginwatcher) GetInfo -> (pluginwatcher) NotifyRegistrationStatus -> (deviceplugin) ListWatch
```
Rather than
```
(pluginwatcher) GetInfo (race) -> (pluginwatcher) NotifyRegistrationStatus
(race) -> (deviceplugin) ListWatch
```
This PR changes the callback/channel mechanism to a more explicit, interfaced based contract (and more maintainable than a function to which we add more channels for more lifecycle events).
This PR also introduces three new states: {Init, Register, DeRegister}
```golang
// PluginHandler is an interface a client of the pluginwatcher API needs to implement in
// order to consume plugins
// The PluginHandler follows the simple following state machine:
//
// +--------------------------------------+
// | ReRegistration |
// | Socket created with same plugin name |
// | |
// | |
// Socket Created v + Socket Deleted
// +------------------> Validate +----------> Init +---------> Register +------------------> DeRegister
// + + +
// | | |
// | Error | Error |
// | | |
// v v v
// Out Out Out
//
// The pluginwatcher module follows strictly and sequentially this state machine for each *plugin name*.
// e.g: If you are Registering a plugin foo, you cannot get a DeRegister call for plugin foo
// until the Register("foo") call returns. Nor will you get a Validate("foo", "Different endpoint", ...)
// call until the Register("foo") call returns.
//
// ReRegistration: Socket created with same plugin name, usually for a plugin update
// e.g: plugin with name foo registers at foo.com/foo-1.9.7 later a plugin with name foo
// registers at foo.com/foo-1.9.9
//
// DeRegistration: When ReRegistration happens only the deletion of the new socket will trigger a DeRegister call
type PluginHandler interface {
// Validate returns an error if the information provided by
// the potential plugin is erroneous (unsupported version, ...)
ValidatePlugin(pluginName string, endpoint string, versions []string) error
// Init starts the plugin (e.g: contact the gRPC client, gets plugin
// specific information, ...) but if another plugin with the same name
// exists does not switch to the newer one.
// Any error encountered here can still be Notified to the plugin.
InitPlugin(pluginName string, endpoint string) error
// Register is called once the pluginwatcher has notified the plugin
// of its successful registration.
// Errors at this point can no longer be bubbled up to the plugin
RegisterPlugin(pluginName, endpoint string)
// DeRegister is called once the pluginwatcher observes that the socket has
// been deleted.
DeRegisterPlugin(pluginName string)
}
```
