Enable service account signing key rotation
fixes#21007
```release-note
The kube-apiserver --service-account-key-file option can be specified multiple times, or can point to a file containing multiple keys, to enable rotation of signing keys.
```
This PR enables the apiserver authenticator to verify service account tokens signed by different private keys. This can be done two different ways:
* including multiple keys in the specified keyfile (e.g. `--service-account-key-file=keys.pem`)
* specifying multiple key files (e.g. `--service-account-key-file current-key.pem --service-account-key-file=old-key.pem`)
This is part of enabling signing key rotation:
1. update apiserver(s) to verify tokens signed with a new public key while still allowing tokens signed with the current public key (which is what this PR enables)
2. give controllermanager the new private key to sign new tokens with
3. remove old service account tokens (determined by verifying signature or by checking creationTimestamp) once they are no longer in use (determined using garbage collection or magic) or some other algorithm (24 hours after rotation, etc). For the deletion to immediately revoke the token, `--service-account-lookup` must be enabled on the apiserver.
4. once all old tokens are gone, update apiservers again, removing the old public key.

Run flaky tests in parallel
We should try to emulate the main CI environment in the flaky test suite so that it is clear when a test can be moved out of the flaky suite. Since a common source of flakes is unintended interactions between tests running in parallel, we should run the flaky suite in parallel to better detect such flakes.

Bump kubeadm to use kubernetes v1.4.1
v1.4.1 is going to be released tomorrow, so make kubeadm use it by default
This will make it possible to run kubeadm on Raspberry Pi's OOTB
We should strive towards releasing a second kubeadm release this week that's stable and has the small new tweaks we've coded these two weeks.

log-dump.sh: Add a LOG_DUMP_USE_KUBECTL mode, refactor
**What this PR does / why we need it**: This refactors log-dump.sh so that it can optionally just use `"kubectl get node"` output, for dumping logs off a cluster that was brought up using something other than kube-up.sh (e.g. kops or kubeadm).
Note that for obvious reasons, if the cluster is fried, it'll probably fail to hit the apiserver and all bets are off, but for the 95% case where you're debugging tests, this is good. To cover the remaining 5%, you could actually squirrel away the relevant external IPs after the e2e.go:Up stage (because we better be able to hit the apiserver then) and fetch them from cache later.
**Special notes for your reviewer**: Sorry for so many changes. :)

We can then avoid the following warning:
```
WARNING: The '--' argument must be specified between gcloud specific args on the left and DOCKER_ARGS on the right. 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.

Few usability improvements:
- Added a proxy to enable viewing worker logs
- Removed seperate webui service
- Modified Zeppelin and spark-ui services to be Loadbalancers
- Changed pyspark example to be platform agnostic
- Improved kubectl context setup
- Minor grammar/flow fixes

openstack: Support config-drive and improve CurrentNodeName, GetZone
This PR adds support for fetching local instance metadata via config-drive (as well as querying metadata service), and surfaces some additional metadata information (from either source):
- `CurrentNodeName` now returns the OpenStack instance name, rather than the current hostname (they might not be the same)
- `GetZone` includes availability zone label in `FailureDomain`
Thanks to @kiall for a WIP implementation of the latter.
Previously, we used the docker config digest (also called "image ID"
by Docker) for the value of the `ImageID` field in the container status.
This was not particularly useful, since the config manifest is not
what's used to identify the image in a registry, which uses the manifest
digest instead. Docker 1.12+ always populates the RepoDigests field
with the manifest digests, and Docker 1.10 and 1.11 populate it when
images are pulled by digest.
This commit changes `ImageID` to point to the the manifest digest when
available, using the prefix `docker-pullable://` (instead of
`docker://`)
Previously, the `InspectImage` method of the Docker interface expected a
"pullable" image ref (name, tag, or manifest digest). If you tried to
inspect an image by its ID (config digest), the inspect would fail to
validate the image against the input identifier. This commit changes
the original method to be named `InspectImageByRef`, and introduces a
new method called `InspectImageByID` which validates that the input
identifier was an image ID.

**What this PR does / why we need it**:
This is a continuation of #34049, which worked, but then I realized some patch files have more than one subject, see example: https://github.com/kubernetes/kubernetes/pull/34228
This cleans the output so it looks like this:
```

Use nodeutil.GetHostIP consistently when talking to nodes
Most of our communications from apiserver -> nodes used
nodutil.GetNodeHostIP, but a few places didn't - and this meant that the
node name needed to be resolvable _and_ we needed to populate valid IP
addresses.
```release-note
The apiserver now uses addresses reported by the kubelet in the Node object's status for apiserver->kubelet communications, rather than the name of the Node object. The address type used defaults to `InternalIP`, `ExternalIP`, and `LegacyHostIP` address types, in that order.
```
The original fix (#33147) sourced the correct `node-helper.sh` but set
`node_os_distribution` instead of `NODE_OS_DISTRIBUTION`. The
`set-node-image` function is imported indirectly via `source
"${KUBE_ROOT}/cluster/kube-util.sh"`, which in turn (in the GCE case)
sources `cluster/gce/util.sh`. Since the `set-node-image` function
relies on the `NODE_OS_DISTRIBUTION` variable, the original fix
did not have the entire intended effect.
I have confirmed that cherry-picking #33147 into the `release-1.4`
branch and layering this commit on top of it make for a successful
upgrade from a GCI based K8s 1.3 cluster to a GCI based K8s 1.4 cluster.

Federated deployment controller - part 1
Based on federated replicaset controller (copy + find/replace).
Remaining stuff:
- refacing out common elements to libs
- using owerref in pod analysis
- e2e tests
- renaming concurrency flag for rs and reusing it in deployment
- updating only one cluster at a time if rollingupdate strategy is used.

```release-note
Federated deployment controller that supports the same api as the regular kubernetes deployment controller.
