Remove federation
This PR removes the federation codebase and associated tooling from the tree.
The first commit just removes the `federation` path and should be uncontroversial. The second commit removes references and associated tooling and suggests careful review.
Requirements for merge:
- [x] Bazel jobs no longer hard-code federation as a target ([test infra #4983](https://github.com/kubernetes/test-infra/pull/4983))
- [x] `federation-e2e` jobs are not run by default for k/k
**Release note**:
```release-note
Development of Kubernetes Federation has moved to github.com/kubernetes/federation. This move out of tree also means that Federation will begin releasing separately from Kubernetes. The impact of this is Federation-specific behavior will no longer be included in kubectl, kubefed will no longer be released as part of Kubernetes, and the Federation servers will no longer be included in the hyperkube binary and image.

Fallback to internal addrs in e2e tests when no external addrs available
This change modifies the way that config.NodeIP is selected at the
start of e2e Networking tests such that if no external addresses are
available from the cloud provider (e.g. either no cloud provider being
used [baremetal or VMs], or the provider doesn't have external IPs
configured), then one of the internal addresses is used.
Without this change, the e2e service-related Networking tests will always
panic when config.ExternalAddrs[0] is accessed and the slice is empty.
This change eliminates the panic, and in some setups, the fallback choice
of using an internal address will provide the necessary connectivity
for the e2e Networking tests to access each node.

move webhook admission to generic apiserver
This builds on https://github.com/kubernetes/kubernetes/pull/54414.
It moves the admission webhook into the generic apiserver. It also allows the injection of a server managed way to override the rest.Config used for a particular service. This makes for an easier point to allow auto-configuration of the kube-apiserver to loopback to itself as a special case for kubernetes.default.svc.

ScaleIO - Ability to specify Secret's name and namespace

This PR is to decouple the ScaleIO secret from the same namespace as that of the StorageClass/PVC/PV that uses it (#53619).

This PR introduces secret parameter that allows specification of secret's namespace.

As we add more feature gates, there might be occasions where a feature is only available on newer releases of K8s. If a user makes a mistake, we should notify them as soon as possible in the init procedure and not them go down the path of hard-to-debug component issues.

Removed containers are not always waiting
fixes#54499
The issue was that a container that is removed (during pod deletion, for example), is assumed to be in a "waiting" state.
Instead, we should use the previous container state.
Fetching the most recent status is required to ensure that we accurately reflect the previous state. The status attached to a pod object is often stale.
I verified this by looking through the kubelet logs during a deletion, and verifying that the status updates do not transition from terminated -> pending.

if d < 0 {

```
it is expected to go on sleep for some time if not meet the minPeriod. However, if time happens hops to the past in the process. `d := time.Since(r.lastErrorTime)` would be a negative number, thus, it may sleep a lot longer than we expected.
The period for sleep should be reseted if time hops
