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.

Ensure object returned by volume getCloudProvider incorporates cloud config
This PR addresses https://github.com/kubernetes/kubernetes/issues/23517.
**Problem**
The existing GCE PD and AWS EBS volume plugin code were fetching cloud provider without specifying a cloud config: `cloudprovider.GetCloudProvider("gce", nil)`
This caused the cloud provider to use default auth mechanism, which is not acceptable for the provisioning controller running on GKE master.
**Fix**
This PR does the following:
* Modifies the GCE PD and AWS EBS volume plugin code to use the cloud provider object pre-constructed by the binary with a cloud config.
* Enable provisioning E2E test for GKE (to catch future issues).
Thanks to @cjcullen for debugging and finding the root cause! 👍
This should be cherry-picked into the v1.2 branch for the next release.

support NETWORK_PROVIDER=cni for KUBERNETES_PROVIDER=vagrant
While trying to develop CNI plugins for K8's, I found the docs referenced the support of --network-plugin=cni for kubelet, but this wasn't surfaced up via salt to support env NETWORK_PROVIDER=cni before a kube-up deployment.
This PR is my attempt at adding CNI support to the kube-up happy path, following a lot of similar work for NETWORK_PROVIDER=kubenet which already exists.
Also, I've added the ability to consume CNI plugin's (binaries) and configuration files from the local cluster/network-plugins directory into the necessary locations as referenced here for CNI:
http://kubernetes.io/docs/admin/network-plugins
This allows a local developer to easily work on CNI plugin development while following the existing kube-up.sh docs and process.
In general, i've struggled to find any authoritative information or answers to my questions in slack regarding CNI progress / correct integration, so comments encouraged here!
Files are taken from cluster/network-plugins/{bin,conf} to be consumed within a vagrant kube-up.sh environment.
Paths used for configuration files and the 'cni' name of the network provider are all from the kubernetes documentation, but the actual implementation in the salt automation doesn't seem to exist.
Use of NETWORK_PROVIDER=cni is documented as useable (as well as it's affects on the runtime args of kubelet),
however the actual implimentation in the salt automation doesnt seem to exist.
this change attempts to fix that for the vagrant usecase.

Add zsh completion for kubectl
This is based on the zsh emulation of the bash completion system (compare `bashcompinit` at http://zsh.sourceforge.net/Doc/Release/Completion-System.html). Because this emulation is not 100% complete, a number of functions are added or extended to work with the bash completion of kubectl.

Kubelet: Remove nsinit related code and bump up minimum docker apiversion
Docker has native exec support after 1.3.x. We never need this code now.
As for the apiversion, because Kubernetes supports 1.8.x - 1.10.x now, we should bump up the minimum docker apiversion.
@yujuhong I checked the [changes](https://github.com/docker/engine-api/blob/master/types/versions/v1p20/types.go), we are not relying on any of those changes. So #23506 should work with docker 1.8.x+

use apply instead of create to setup namespaces and tokens in addon manager
when the addon manager restarts, it takes ~15 minutes (1000 seconds) to start the sync loop because it retries creation of namespace and tokens 100 times. Create fails if the tokens already exist. Just use apply.

Move typed clients into clientset folder
Move typed clients from `pkg/client/typed/` to `pkg/client/clientset_generated/${clientset_name}/typed`.
The first commit changes the client-gen, the last commit updates the doc, other commits are just moving things around.
