Remove dead code in `pkg/registry/generic/registry/store.go`

Fixes #38822

Depending on the intent of the original code, the correct fix may instead be:

```go
if name, ok := p.MatchesSingle(); ok {
	key, err := e.KeyFunc(ctx, name)
	if err != nil {
		return nil, err
	}
	w, err := e.Storage.Watch(ctx, key, resourceVersion, p)
	if err != nil {
		return nil, err
	}
	if e.Decorator != nil {
		return newDecoratedWatcher(w, e.Decorator), nil
	}
	return w, nil
	// if we cannot extract a key based on the current context, the optimization is skipped
}
```

genericapiserver: turn APIContainer.SecretRoutes into a real ServeMux

The secret routes `Mux` is actually a `http.ServeMux` and we are type-casting to it. For downstream we want to wrap it into a restful container which also needs a real `http.ServeMux`.

Fix Recreate for Deployments and stop using events in e2e tests

Fixes https://github.com/kubernetes/kubernetes/issues/36453 by removing events from the deployment tests. The test about events during a Rolling deployment is redundant so I just removed it (we already have another test specifically for Rolling deployments).

Closes https://github.com/kubernetes/kubernetes/issues/32567 (preferred to use pod LISTs instead of a new status API field for replica sets that would add many more writes to replica sets).

[Federation] Stop cleaning federation namespace in e2e tests

when --clean-start=true flag is provided to e2e tests it would cleanup all the leftover namespaces except `default` and `kube-system` and because of this when we run e2e tests in federation soak test job, the federation control plane is destroyed before it runs the tests and all tests start to fail.

So adding federation-system to the list of namespace to be left intact and also changed the default federation namespace name from `federation` to `federation-system` to be consistent with the newer method of deploying federation using kubefed.

[Federation][init-11.2] use USE_KUBEFED env var to choose bw old and new federation deployment

This is continuation of #35961
USE_KUBEFED variable is used for deploying federation control plane. if not defined, federation will be brought up using old method i.e scripts.

Have verified that federation comes up using the old method, using following steps
```
$ export FEDERATION=true
$ export E2E_ZONES="asia-east1-c"
$ export FEDERATION_PUSH_REPO_BASE=gcr.io/<my-project>
$ KUBE_RELEASE_RUN_TESTS=n KUBE_FASTBUILD=true go run hack/e2e.go -v -build
$ build-tools/push-federation-images.sh
$ go run hack/e2e.go -v --up

kubeadm: refactor discovery behind an interface

This adds support for alternative discovery methods using discovery urls. It is a breaking change. This is a WIP.

Example usage:
```
$ kubeadm init --discovery token://
$ kubeadm join --discovery token://c05de9:ab224260fb3cd718@192.168.0.1:6555,191.168.0.2:6443
$ kubeadm join --discovery file:///etc/kubernetes/cluster.json

make kubectl factory composeable

Alternate resolution of https://github.com/kubernetes/kubernetes/pull/38524.

Currently, the kubectl factory cannot be cleanly composed because without polymorphism, any calls which delegate to other factory methods cannot injected.  We cannot reasonably predict everything a composer would want to override, so enumeration of individual "we think this field is important" function is untenable.  On the other hand, having a method registry func and attaching methods to it resulted in chaos before 1.5 and the cleaner interface.

This pull takes the approach of building the factory in "rings" of subfactories.  RingN relies on RingN-1 and the overall factory is a set of nested factories.  No function in a "ring" is allowed to reference a peer function, but it may reference a parent ring's function.  This allows us to easily compose one chain for raw kube, but an extender can simply wrap a particular ring with his custom handling of particular functions and then continue the chain as normal.  This allows customization of each individual function.

It turns out that we have three rings.
 1. discovery, negotiation, and no-dep functions
 1. object typing and type mapping
 1. stuff that relies on type mapping (builder)

This pull does nothing split apart the dependencies.  No behavior changes.  There's more cleanup that could be done (particularly in naming), but I'd like to defer that to a later step.

@kubernetes/sig-cli @fabianofranz @AdoHe this is going to be a pain to rebase, so quick reviews are appreciated.

Rename build-tools/debs to build/debs

hack/dev-build-*: Run dev build instead of release build

The current dev-build-*.sh scripts do a full release build which means
running tests and also doing cross-platform builds.  This is unnecessary
and after discussing this in Slack it was suggested to either blow away
these files or fix them.  This should fix them.

It turns out that `docker save $IMAGE -o $FILE` only works for docker 1.12. (My desktop is 1.12) For older version docker, we should use `docker save -o $FILE $IMAGE instead`. (Jenkins is using 1.9.1)
