Use the core client with explicit version globally
**What this PR does / why we need it**:
As mentioned in #49535 and #50605, we want to have a global replace to use core client with explicit version.
**Which issue this PR fixes**: fixes#49535
**Special notes for your reviewer**:
The actual type of clientSet.Core() is already the same with clientSet.CoreV1(), so it should be safe replacement.
The places that clientSet.Core() are still in use are identified by IDE "find usages", and changes are made with one time global replace. Hopefully there will be none left after this PR merged.
Let me know if this PR is too big to review, I can split it into some smaller ones.

RBD Plugin: Implement Attacher/Detacher interfaces.
**What this PR does / why we need it**:
This PR continues @rootfs 's work in #33660. It implements volume.Attacher/Volume.Detacher interfaces to resolve RBD image locking and makes RBD plugin more robust.
Summary of interfaces and what they do for RBD plugin:
- Attacher.Attach(): does nothing
- Attacher.VolumesAreAttached(): method to query volume attach status
- Attacher.GetDeviceMountPath(): method to get device mount path
- Attacher.WaitForAttach(): kubelet maps the image on the node (and lock the image if needed)
- Attacher.MountDevice(): kubelet mounts device at the device mount path
- Detacher.UnmountDevice: kubelet unmounts device from the device mount path (currently, we need to unmaps image from the node here) (and unlock the image if needed)
- Detacher.Detach(): does nothing
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #
fixes#50142.
**Special notes for your reviewer**:
RBD changes:
1) Modify rbdPlugin to implement volume.AttachableVolumePlugin interface.
2) Add rbdAttacher/rbdDetacher structs to implement
volume.Attacher/Detacher interfaces.
3) Add mount.SafeFormatAndMount/mount.Exec fields to rbdPlugin, and setup them in
rbdPlugin.Init for later uses. Attacher/Mounter/Unmounter/Detacher
reference rbdPlugin to use mounter and exec. This simplifies
code.
4) Add testcase struct to abstract RBD Plugin test case, etc.
5) Add newRBD constructor to unify rbd struct initialization.
Non-RBD changes:
1) Fix FakeMounter.IsLikelyNotMountPoint to return ErrNotExist if the
directory does not exist. Mounter.IsLikelyNotMountPoint interface
requires this, and RBD plugin depends on it.
2) ~~Extend Detacher.Detach method to pass `*volume.Spec`, RBD plugin
needs it to detach device from the node.~~
3) ~~Extend Volume.Spec struct to include namespace string, RBD Plugin needs
it to locate objects (e.g. secrets) in Pod's namespace.~~
4) ~~Update RABC bootstrap policy to allow
`system:controller:attachdetach-controller` cluster role to get
Secrets object. RBD attach/detach needs to access secrets object in
Pod's namespace.~~

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.

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

Add HA feature gate and minVersion validation
**What this PR does / why we need it**:
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.
Specifically with HA, we ideally need the new `TaintNodesByCondition` (added in v1.8.0 but working in v1.9.0).
**Which issue this PR fixes:**
kubernetes/kubeadm#261kubernetes/kubeadm#277
**Release note**:
```release-note
Feature gates now check minimum versions
```
