Extract gnu-sed detection into a function
**What this PR does / why we need it**:
Moves gnu-sed detection into a reusable function across scripts (considering it's in multiple places).

When the verify scripts fail to install a component using `go get`
today, they silence output go `stderr` and cause the user to not get any
actionable feedback on failure.

[Federation][Kubefed] Support reference document autogeneration for kubefed
This PR is needed to address the documentation issue https://github.com/kubernetes/kubernetes.github.io/issues/2888
Apart from the code auto generation have updated some descriptions for consistency.

hack/local-up-cluster.sh uses cfssl to generate certificates and
will exit it cfssl is not already installed. But other cluster-up
mechanisms (GCE) that generate certs just download cfssl if not
present. Make local-up-cluster.sh do that too.
Per Clayton's suggestion, move stuff from cluster/lib/util.sh to
hack/lib/util.sh. Also consolidate ensure-temp-dir and use the
hack/lib/util.sh implementation rather than cluster/common.sh.

Don't try to run hack/verify-staging-* on dirty repository
When the repo is dirty after running all `update-*` scripts in `hack/update-all.sh`, the staging verify scripts still fail. This PR removes these from `hack/update-all.sh`. Instead give useful instructions or continue automatically with `hack/update-all-staging.sh`.

Build release tars using bazel
**What this PR does / why we need it**: builds equivalents of the various kubernetes release tarballs, solely using bazel.
For example, you can now do
```console
$ make bazel-release
$ hack/e2e.go -v -up -test -down
```
**Special notes for your reviewer**: this is currently dependent on 3b29803eb5, which I have yet to turn into a pull request, since I'm still trying to figure out if this is the best approach.
Basically, the issue comes up with the way we generate the various server docker image tarfiles and load them on nodes:
* we `md5sum` the binary being encapsulated (e.g. kube-proxy) and save that to `$binary.docker_tag` in the server tarball
* we then build the docker image and tag using that md5sum (e.g. `gcr.io/google_containers/kube-proxy:$MD5SUM`)
* we `docker save` this image, which embeds the full tag in the `$binary.tar` file.
* on cluster startup, we `docker load` these tarballs, which are loaded with the tag that we'd created at build time. the nodes then use the `$binary.docker_tag` file to find the right image.
With the current bazel `docker_build` rule, the tag isn't saved in the docker image tar, so the node is unable to find the image after `docker load`ing it.
My changes to the rule save the tag in the docker image tar, though I don't know if there are subtle issues with it. (Maybe we want to only tag when `--stamp` is given?)
Also, the docker images produced by bazel have the timestamp set to the unix epoch, which is not great for debugging. Might be another thing to change with a `--stamp`.
Long story short, we probably need to follow up with bazel folks on the best way to solve this problem.

from etcd.sh split the start process into validate fucntion + start function so that the validate piece can be reused elsewhere. the up-cluster script has been changed to remove duplicate docker logic to the one used in buid-tools/common.sh and the validate etcd function is now used here.
moved docker daemon check function to util.sh and made function name changes and upstream changes.

Retry curl when it failed during download
Fixes#34769
For now I'm adding retry only to etcd installation as I saw it recently to fail in one of my PRs. We may change it also in other places if it also happens.
Generate a kubeconfig for use with controller-manager, kubelet,
scheduler etc. This kubeconfig should use the secure https
port of the api server with appropriate ca cert for the components
to talk to api server.
With this change, one can set API_PORT=0 to completely switch off
insecure access for testing admission controllers etc.
