[Federation] Remove FEDERATIONS_DOMAIN_MAP references
Remove all references to FEDERATIONS_DOMAIN_MAP as this method is no longer is used and is replaced by adding federation domain map to kube-dns configmap.
cc @madhusudancs @kubernetes/sig-federation-pr-reviews
**Release note**:
```
[Federation] Mechanism of adding `federation domain maps` to kube-dns deployment via `--federations` flag is superseded by adding/updating `federations` key in `kube-system/kube-dns` configmap. If user is using kubefed tool to join cluster federation, adding federation domain maps to kube-dns is already taken care by `kubefed join` and does not need further action.

Silence error messages from the docker rmi call we expect to fail
**What this PR does / why we need it**: when we removed `docker tag -f` in #34361 we added a bunch of `docker rmi` calls to preserve behavior for older docker versions. That step is usually a no-op, however, and results in confusing messages like
```
Tagging docker image gcr.io/google_containers/kube-proxy:c8d0b2e7a06b451117a8ac58fc3bb3d3 as gcr.io/kubernetes-release-test/kube-proxy-amd64:v1.5.4
Error response from daemon: No such image: gcr.io/kubernetes-release-test/kube-proxy-amd64:v1.5.4
```
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes#42665
**Special notes for your reviewer**: I could probably remove the `docker rmi` calls entirely, though I don't know if folks are still using docker < 1.10. (I think Jenkins still has 1.9.1.)
**Release note**:
```release-note

Remove the kube-discovery binary from the tree
**What this PR does / why we need it**:
kube-discovery was a temporary solution to implementing proposal: https://github.com/kubernetes/community/blob/master/contributors/design-proposals/bootstrap-discovery.md
However, this functionality is now gonna be implemented in the core for v1.6 and will fully replace kube-discovery:
- https://github.com/kubernetes/kubernetes/pull/36101
- https://github.com/kubernetes/kubernetes/pull/41281
- https://github.com/kubernetes/kubernetes/pull/41417
So due to that `kube-discovery` isn't used in any v1.6 code, it should be removed.
The image `gcr.io/google_containers/kube-discovery-${ARCH}:1.0` should and will continue to exist so kubeadm <= v1.5 continues to work.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #
**Special notes for your reviewer**:
**Release note**:
```release-note
Remove cmd/kube-discovery from the tree since it's not necessary anymore

Base etcd-empty-dir-cleanup on busybox, run as nobody, and update to etcdctl 3.0.14
**What this PR does / why we need it**: since the `etcd-empty-dir-cleanup` image just uses a simple shell script and `etcdctl`, we can base it on busybox, which is a smaller target than alpine.
I've also updated this to use an `etcdctl` from etcd 3.0.14, which matches the version of etcd we're running in 1.6 clusters (I believe), and changed the tag to match the `etcdctl` version.
Tested in my own e2e cluster, where it seems to work.
I haven't pushed the image yet, so e2e tests *may* fail. Tagging `do-not-merge`; if you think this looks good, I'll push the image and retest.
**Release note**:
```release-note

Update kubectl in addon-manager to use HPA in autoscaling/v1
Addon-manager is broken since HPA objects were removed from extensions api group.
Came across the logs from [the latest addon-manager on Jenkins](https://storage.googleapis.com/kubernetes-jenkins/logs/ci-kubernetes-e2e-gci-gce/4290/artifacts/bootstrap-e2e-master/kube-addon-manager.log):

```
And notice this commit (f66679a4e9) came in two weeks ago, which removed HorizontalPodAutoscaler from extensions/v1beta1.
Addon-manager is now partially functioning that it could successfully create and update addons, but will fail to prune objects, which means upgrade tests may mostly fail.
Pushed another version of addon-manager with kubectl v1.6.0-alpha.2 ([release 2 days ago](https://github.com/kubernetes/kubernetes/releases/tag/v1.6.0-alpha.2)) for fixing, including below images:
- gcr.io/google-containers/kube-addon-manager:v6.4-alpha.2

Added a basic monitor for providing etcd version related info
Fixes#41071
This tool scrapes metrics partly from etcd's /version and /metrics endpoints and partly using etcdctl and exposes them as prometheus metrics at `http://localhost:9101/metrics` endpoint on the master. Here is a summary of the metrics it exposes (self-explanatory from the code):
- etcdVersionFetchCount = prometheus.NewCounterVec(
prometheus.CounterOpts{
Namespace: "etcd",
Name: "version_info_fetch_count",
Help: "Number of times etcd's version info was fetched, labeled by etcd's server binary and cluster version",
},
[]string{"serverversion", "clusterversion"})
- etcdGRPCRequestsTotal = prometheus.NewCounterVec(
prometheus.CounterOpts{
Namespace: namespace,
Name: "grpc_requests_total",
Help: "Counter of received grpc requests, labeled by grpc method and grpc service names",
},
[]string{"grpc_method", "grpc_service"})
For further info on how to run this as a binary/docker-container/kubernetes-pod and checking the metrics, have a look at the README.md file.

Change the etcd rollback tool to do rollback to 2.2.1 version.
I did some tests of it and for my 3-node cluster with 1 deployment it worked fine.
But before merging this, we should probably do way more testing (we should rerun tests that @mml was doing for the previous script).

Add alternative names for the server binaries to hyperkube
**What this PR does / why we need it**:
Right now one can't swap a server image to the hyperkube image without touching the `command` field in the yaml spec, and that's daunting and leading to extra and unnecessary logic for example in kubeadm.
This makes the hyperkube image directly swappable, so now `/usr/local/bin/kube-*` is a portable first argument (or simply `kube-*` if there's a shell).
**Special notes for your reviewer**:
**Release note**:
```release-note
Align the hyperkube image to support running binaries at /usr/local/bin/ like the other server images
```

-->
**What this PR does / why we need it**: This PR enables s390x support to kube-dns , pause, addon-manager, etcd, hyperkube, kube-discovery etc. This PR also includes the changes due to which it can be cross compiled on x86 host architecture.
**Which issue this PR fixes#34328
**Special notes for your reviewer**: In existing file "build-tools/build-image/cross/Dockerfile" the repository mentioned for installing cross build tool chains for supporting architecture does not have a tool chain for s390x hence in my PR I am changing the repository so that it will be cross compiled for s390x.
**Release note**:
<!-- Steps to write your release note:
1. Use the release-note-* labels to set the release note state (if you have access)
2. Enter your extended release note in the below block; leaving it blank means using the PR title as the release note. If no release note is required, just write `NONE`.

Do not cache hyperkube package installation
**What this PR does / why we need it**:
The hyperkube build process could use a cached layer containing out of date packages. For example, the v1.4.0 image contains packages with security vulnerabilities, which should have been available as of the release build date.
This was surfaced from quay.io/clair scanning the hyperkube images:
17bc61b54e047da8cd1b23316aac6961db?tab=vulnerabilities
This patch adds a cache-busting comment to the RUN command which installs/updates packages.

IMPORTANT: previously, commands allowed the omission of the --, and unparsed arguments were treated as implementation args. This usage is being deprecated and will be removed in March 2017.
This will be strictly enforced in March 2017. Use 'gcloud beta docker' to see new behavior.
