move client/record

An attempt at moving client/record to client-go.  It's proving very stubborn and needs a lot manual intervention and near as I can tell, no one actually gets any benefit from the sink and source complexity it adds.

Change OPENSTACK_IMAGE_NAME to be more specific

There may already be other images in the cloud named CentOS7,
but since we are fetching a very specific version (1604) we should
go ahead and make the image name very specific as well.



**What this PR does / why we need it**:

Some clouds already have `Centos7` as an image that is available, however it may not be the *specific* version that openstack-heat looks for and downloads from CentOS.

**Special notes for your reviewer**:

**Release note**:

```release-note 
OpenStack-Heat will now look for an image named "CentOS-7-x86_64-GenericCloud-1604". To restore the previous behavior set OPENSTACK_IMAGE_NAME="CentOS7"

Preventing nil pointer reference in client_config

When a user tries to set the `extensions` map in the kube config, loading of the client config causes nil pointer exception because the `Context`, `Cluster`, `AuthInfo` objects are created without initializing the extensions map. This PR attempts to fix that.

Removed Flaky tag from PV e2e, added [Volume] to disruptive PV e2e

**What this PR does / why we need it**:
Removes `[Flaky]` from PV e2e testing.  Flakes were due to interference from an external test disrupting a cluster node.  The test has been [removed](https://github.com/rmmh/kubernetes/commit/9f36c032de8c45beb02412d5abf870943023f6c4) and the flakes have [cleared](https://k8s-testgrid.appspot.com/google-gce#gce-flaky).

Secondly, added `[Volume]` tag to PV disruptive tests.

test/images/mount-tester: ensure exec binary is o+rx

The `mount-tester` image is currently used as a base layer for other
test images (like `mounttest-user`) which perform uid/gid changes.
However, the binary built in here just follows local umask, and currently is
```
-rwxr-x--- 1 root root 2052704 May 19  2016 mt
```

This commit adds an explicit chmod on the binary to make sure uid/gid
tests can still run it as "others".

e2e test should fail if err==timeout

If err==timeout, it means the replicaset (the owner) is not deleted after 30s, which indicates a bug, so the e2e test should fail.
