So multiple instances of kube-apiserver can bind on the same address and
port, to provide seamless upgrades.

Remove the "OrDie" from the name (since it doesn't "or die") and add
an extra check that there is at least 1 node available, since many
callers already did that themselves, and many others should have.
The test package imports cmd/kubeadm, which is far from ideal.
There are a couple of reasons for the import:
1) Marshaling of Ingress from api/extensions/v1beta1.
To fix that include a local function in e2e/manifest/manifest.go
that does that same as the kubeadm MarshalToYaml.
2) Using PKI helper function in apimachinery and auth tests.
To fix that include a new file under test/utils/pki_helpers.go
that only contains the required helpers instead of including the whole
kubeadm pkiutil package.
There is another related problem:
e2e_node/e2e_node_suite_test.go includes:
k8s.io/kubernetes/cmd/kubeadm/app/util/system
But this has to be done in a follow up.
This PR is the first step to transition CSINodeInfo and CSIDriver
CRD's to in-tree APIs. It adds them to the existing API group
“storage.k8s.io” as core storage APIs.
This package contains public/private key utilities copied directly from
client-go/util/cert. All imports were updated.
Future PRs will actually refactor the libraries.
Updates #71004
is either decided by the schema's version priority, or by the per
resource override.
This fixes a bug where the "batch" group is encoded in v1beta1, which
was hidden when --storage-versions is a valid flag.
When we are running apiserver related code, we do not currently capture
the logs from `httplog.NewLogged` and `trace.LogIfLong` since the
default log verbosity is not set. So just make sure we have a minimum
verbosity set in these circumstance.

- Move from the old github.com/golang/glog to k8s.io/klog
- klog as explicit InitFlags() so we add them as necessary
- we update the other repositories that we vendor that made a similar
change from glog to klog

* k8s.io/gengo/
* k8s.io/kube-openapi/
* github.com/google/cadvisor
- Entirely remove all references to glog

The EtcdMain function in integration tests is designed to launch an etcd
instance only when running in a bazel test. For non-bazel, we rely on
hack/make-rules/test-integration.sh to bring up the etcd instance.
This patch fixes the following in EtcdMain:
1. If etcd is not found in ${RUNFILES_DIR} then look in ${PATH}.
2. Try to connect to the etcd started by `make test-integraion`; if it
is up, then don't start etcd.
3. Gracefully shut down etcd after tests.
4. Get a port from the OS instead of deriving it from argv[0].
5. Don't use sync.Once.
The benefit of this change is that integration tests work with `go test`
as well as `make test-integration` without users needing to do anything
special. That makes it much easier to pass go testing flags to tests and
integrate with IDEs.

controller-manager: switch to options+config pattern and add https+auth
This PR switch the {kube,cloud}-controller-managers to use the Options+Config struct pattern for bootstrapping, as we use it throughout all apiservers. This allows us to easily plug in https and authn/z support.

This is the 2nd attempt. The previous was reverted while we figured out
the regional mirrors (oops).
New plan: k8s.gcr.io is a read-only facade that auto-detects your source
region (us, eu, or asia for now) and pulls from the closest. To publish
an image, push k8s-staging.gcr.io and it will be synced to the regionals
automatically (similar to today). For now the staging is an alias to
gcr.io/google_containers (the legacy URL).
When we move off of google-owned projects (working on it), then we just
do a one-time sync, and change the google-internal config, and nobody
outside should notice.
We can, in parallel, change the auto-sync into a manual sync - send a PR
to "promote" something from staging, and a bot activates it. Nice and
visible, easy to keep track of.

note that we don't change the behaviour of kubectl.
For example it won't scale new resources. That's the end goal.

Replace hand-written informers with generated ones
Replace existing uses of hand-written informers with generated ones.
Follow-up commits will switch the use of one-off informers to shared
informers.
This is a precursor to #40097. That PR will switch one-off informers to shared informers for the majority of the code base (but not quite all of it...).
NOTE: this does create a second set of shared informers in the kube-controller-manager. This will be resolved back down to a single factory once #40097 is reviewed and merged.
There are a couple of places where I expanded the # of caches we wait for in the calls to `WaitForCacheSync` - please pay attention to those. I also added in a commented-out wait in the attach/detach controller. If @kubernetes/sig-storage-pr-reviews is ok with enabling the waiting, I'll do it (I'll just need to tweak an integration test slightly).
