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
saltbase/salt/kube-dns

Fix hyperkube's layer caching, and remove --make-symlinks at build time
@david-mcmahon This is required before you release. Explanation in the code.

cluster/images/hyperkube: create symlink for each server
Add a kubelet symlink so that the hyperkube image can appear as a kubelet image. https://github.com/kubernetes/kubernetes/issues/24510

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.
