Add admission controller for default storage class.
The admission controller adds a default class to PVCs that do not require any
specific class. This way, users (=PVC authors) do not need to care about
storage classes, administrator can configure a default one and all these PVCs
that do not care about class will get the default one.
The marker of default class is annotation "volume.beta.kubernetes.io/storage-class", which must be set to "true" to work. All other values (or missing annotation) makes the class non-default.
Based on @thockin's code, added tests and made it not to reject a PVC when no class is marked as default.

fix path handling in hack/lib/init.sh
Jenkinsfile pipeline jobs get cloned into "\<project\> (\<branch\>)". As a result, I can't use certain things in `hack/lib/init.sh`.
This is a small fix for that problem.

Add cleanup addon pod to remove empty keys from etcd
namespace deletion will leave a trace of empty keys on etcd. This PR adds an addon pod to periodically check for those empty keys on etcd and remove them.

Include CNI for all architectures in the hyperkube image
Can some of you (@jfrazelle @mikedanese) quickly lgtm this?
I'd like it if we got it merged before v1.4.0-alpha.2
It's not a huge change, I'm just cross-compiling this CNI stuff while waiting for the v0.4.0 which likely will release binaries for all arches.

Bump the default etcd version in the Makefile to 3.0.3
Fixes: #29132
I haven't had time to manually validate the arm and arm64 version yet, but I think it should be fine.

hyperkube: fix build for 3rd party registry (again)
Fixes issue #28487
This is a minor fix for the issue reported in #28487
Unified skydns templates using a simple underscore based template and
added transform sed scripts to transform into salt and sed yaml
templates
Moved all content out of cluster/addons/dns into build/kube-dns and

Use kube-system namespace
Fixes#23153.
Sadly, kube-system isn't automatically created, so people need to make
sure to create it in their turnup scripts. Also after creating
kube-system it can take 10+ seconds for master and proxy to show up.
I tested the equivalent of these changes locally, but not these changes
themselves as I don't have a dev/build env up, so please read carefully
and maybe try them out!

Up to golang 1.6
A second attempt to upgrade go version above `go1.4`
Merge ASAP after you've cut the `release-1.2` branch and feel ready.
`go1.6` should perform slightly better than `go1.5`, so this time it might work

Cross-build hyperkube and debian-iptables for ARM. Also add a flannel image
We have to be able to build complex docker images too on `amd64` hosts.
Right now we can't build Dockerfiles with `RUN` commands when building for other architectures e.g. ARM.
Resin has a tutorial about this here: https://resin.io/blog/building-arm-containers-on-any-x86-machine-even-dockerhub/
But it's a bit clumsy syntax.
The other alternative would be running this command in a Makefile:
```
# This registers in the kernel that ARM binaries should be run by /usr/bin/qemu-{ARCH}-static
docker run --rm --privileged multiarch/qemu-user-static:register --reset
```
and
```
ADD https://github.com/multiarch/qemu-user-static/releases/download/v2.5.0/x86_64_qemu-arm-static.tar.xz /usr/bin
```
Then the kernel will be able to differ ARM binaries from amd64. When it finds a ARM binary, it will invoke `/usr/bin/qemu-arm-static` first and lets `qemu` translate the ARM syscalls to amd64 ones.
Some code here: https://github.com/multiarch
WDYT is the best approach? If registering `binfmt_misc` in the kernels of the machines is OK, then I think we should go with that.
Otherwise, we'll have to wait for resin's patch to be merged into mainline qemu before we may use the code I have here now.

Fix so setup-files don't recreate/invalidate certificates that already exist
Fixes: #23197 and a lot of other DNS and dashboard issues
This is quite critical for `docker`-based users and should be considered as a **cherrypick-candidate** as it makes a lot of people wonder why Dashboard and/or DNS doesn't work. Example: https://github.com/kubernetes/dashboard/issues/374
Earlier when you shut your `docker.md` cluster down and started it again, all ServiceAccounts became invalidated by `setup-files` that happily ran once again and replaced all files. That made `apiserver` and `controller-manager` pick up the new certs (or there was a race condition, they _could_ have picked up the old certs too, but that's unlikely) and the old certs were put into `/var/run/secrets` because the ServiceAccount's Secrets were stored in etcd, which `setup-files` didn't touch.
