core v1: deprecate the gitRepo volume type
gitRepo stopped accepting new features nearly 2 years ago https://github.com/kubernetes/kubernetes/issues/17676#issuecomment-228650586 and today this behavior can easily be achieved through an init container. The kubelet shelling out to git in the host namespace can also be a security issue on un-trusted repos, as was demonstrated by [CVE-2017-1000117](https://groups.google.com/forum/#!topic/kubernetes-announce/CTLXJ74cu8M). Our own documentation even alludes to this volume type being removed in the future:
> In the future, such volumes may be moved to an even more decoupled model, rather than extending the Kubernetes API for every such use case.
https://kubernetes.io/docs/concepts/storage/volumes/#gitrepo
Closes https://github.com/kubernetes/kubernetes/issues/60999
```release-note-action-required
The GitRepo volume type is deprecated. To provision a container with a git repo, mount an EmptyDir into an InitContainer that clones the repo using git, then mount the EmptyDir into the Pod's container.
```
/release-note-action-required
Instead of this:
```yaml
apiVersion: v1
kind: Pod
metadata:
name: server
spec:
containers:
- image: nginx
name: nginx
volumeMounts:
- mountPath: /mypath
name: git-volume
volumes:
- name: git-volume
gitRepo:
repository: "git@somewhere:me/my-git-repository.git"
revision: "22f1d8406d464b0c0874075539c1f2e96c253775"
```
Do this:
```yaml
apiVersion: v1
kind: ConfigMap
metadata:
name: git-clone
data:
git-clone.sh: |
#!/bin/sh -e
git clone $1 $3
cd $3
git reset --hard $2

use subtest for table units (pkg/master)
**What this PR does / why we need it**:
Go 1.7 added the subtest feature which can make table-driven tests much easier to run and debug. Many table-driven tests in pkg/kubectl are not using this feature.

Ensure that only IPs are used as node addresses in OpenStack LBs
**What this PR does / why we need it**:
ATM, when no InternalIP can be found for a node, the openstack cloud provider tries to create a LB with whatever is the first address it can find for the node. This could also be the hostname or a dns name.
However, LBaaS will reject anything that is not an IP address for pool members. Therefore a meaningful error should be returned instead of just returning the first address of the node, even if it is clear that this will lead to an error in LBaaS.
