Trusty: Handle the new var in kube-proxy manifest
This is to capture the kube-proxy manifest change in PR #24429.
@roberthbailey @fabioy @zmerlynn please review this change and mark it as cherry pick candidate. We need to catch up 1.2.3 release.
cc/ @dchen1107 @wonderfly @cjcullen FYI.
I have verified this fix. Without this fix, kube-proxy pod in Trusty nodes cannot be started correctly, i.e., the command line has an unhadled variable. And some other kube-system pods do not work correctly as kube-proxy is not working well. After applying this fix, kube-proxy can be started correctly, and all kube-system pods run successfully.

Strip comments from configure-vm.sh for gce
We are getting very close to the 32KiB limit on GCE metadata entry length. We used to strip comments before putting the value in metadata, but I think we removed it in a refactor because it wasn't absolutely necessary, and leaving it out made the scripts slightly cleaner. It's close to being necessary again.
Removing comments reduces the size from 31,609B to 27,221B: https://www.diffchecker.com/0xmmecvw.

add HOME env variable for kube-addons service
Fix https://github.com/kubernetes/kubernetes/issues/23973.
Briefly, systemd service does not know the `HOME` environment variable which causes the kubectl write schema file into `/.kube` while it is expected to be `/root/.kube`.

Add easy-rsa to hyperkube container
Otherwise gets downloaded a runtime, which kind of breaks the container model.
See [comment](https://github.com/kubernetes/kubernetes/issues/20514#issuecomment-195835786) in #20514 - this causes dockerized install of k8s to fail if you're behind a proxy. make-ca-cert.sh already looks for a local copy of easy-rsa.tar.gz before downloading it, so this drops the tarball in the expected place in the container.

Fix spacing in usage_from_stdin and info_from_stdin (issue #24186).
If "a" is a bash array, then the syntax to append the contents of $line as a
new element to the array is a+=("$line"), not messages+=$line
Using the former syntax just seems to append to the first element, creating a
long string and thus losing newline information.
Fixing this allows us to drop some empty lines from invocations of
usage_from_stdin.

don't ship kube-registry-proxy and pause images in tars.
pause is built into containervm. if it's not on the machine we should just pull
it. nobody that I'm aware of uses kube-registry-proxy and it makes build/deployment
more complicated and slower.
If "a" is a bash array, then the syntax to append the contents of $line as a
new element to the array is a+=("$line"), not messages+=$line
Using the former syntax just seems to append to the first element, creating a
long string and thus losing newline information.
Fixing this allows us to drop some empty lines from invocations of

Fix GKE kube-up to correctly find an IGM from a multi-zone cluster
I've confirmed that this successfully brings up a cluster, fixing the immediate issue with the new e2e test. Sorry about not properly vetting it in the original PR (#24075).
This does cause a warning message to be printed based on the handling of the NUM_NODES variable though, which I could fix if you guys think it's worth it:
```
Detected 6 ready nodes, found 6 nodes out of expected 3. Found more nodes than expected, your cluster may not behave correctly.
```

Trusty: Fixes for running GKE master
This PR includes two fixes for running GKE master on our image:
(1) The kubelet command line assembly had a missing part for cbr0. We did not catch it because the code path is not covered by OSS k8s tests;
(2) Remove the "" from the variables in the cert files. It causes a parsing issue in GKE. Again, this code path is not covered by k8s tests.
This PR also refactors the code for assembling kubelet flag. I move all logic into a single function assemble_kubelet_flags in configure-helper.sh for better readability and also simplify node.yaml and master.yaml.
@roberthbailey @dchen1107 please review it, and mark it as cherrypick-candidate. This PR is verified by @maisem. Together with his CL for GKE, we can run GKE cluster with master on our image and nodes on ContainerVM.
cc/ @maisem @fabioy @wonderfly FYI
This only applies to gce kube-up. 60 seconds of open connection should
be sufficient for anything that we should be downloading. The release
tar is currently 255M.

Make kube2sky and skydns docker images cross-platform
ARM tracking issue: #17981
Continues on: #19216
Make it possible to create `kube2sky` and `skydns` docker images for ARM and other architectures too
Build in a container, so `golang` isn't a dependency
I've preserved the original default behaviour:
- `skydns`: It just compiles with go on host
- `kube2sky`: Build an image
