Automatic merge from submit-queue
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.

This change revises the way to provide kube-system manifests for clusters on Trusty. Originally, we maintained copies of some manifests under cluster/gce/trusty/kube-manifests, which is not scalable and hard to maintain. With this change, clusters on Trusty will use the same source of manifests as ContainerVM. This change also fixes some minor problems such as shell variables and comments to meet the style guidance better.
To meet licensing/compliance guidelines, bundle up the source. One of
the easiest ways to do this is just to grab the entire build image
directory - this makes it pretty much guaranteed that the user could
re-run the Docker build again from the exact code point if they wanted
to (they just need to poke at our scripts to figure out how).
This change support running kubernetes master on Ubuntu Trusty.
It uses pure cloud-config and shell scripts, and completely gets
rid of saltstack or the release salt tarball.
Use case: I have a docker-machine instance in the cloud, and an empty
DOCKER_OPTS env var. I want to `build/run.sh hack/build-go.sh`
Previously, this would invoke `docker '' cp` which was erroring out
with: '' not a command.
It cordons (marks unschedulable) the given node, and then deletes every
pod on it, optionally using a grace period. It will not delete pods
managed by neither a ReplicationController nor a DaemonSet without the
use of --force.
Also add cordon/uncordon, which just toggle node schedulability.
