Add test coverage to the certificate manager covering the initialization
scenario where it is initialized with no Certificate Request Signing
client, then the client is added later. This matches how it will be used
when the Certificate Request Signing client is also the consumer of the
certificate manager.

Mark kubelet's master-service-namespace flag deprecated
This flag is already deprecated in the API server:
- https://kubernetes.io/docs/admin/kube-apiserver/
- https://kubernetes.io/docs/admin/federation-apiserver/
It doesn't really make sense to adjust this on the Kubelet if you can't change it on the API server anymore.

client.go: format err
**What this PR does / why we need it:**
made the code clean
The order of the storage setup blocks in the setup for the autoscaling
API group was accidentally inverted, meaning that if the v2alpha1 API
group was turned on, it would be set to the preferred API group-version
for discovery.
This was unintentional; the latest stable version should (v1) should be
preferred instead.

Fix hardcoded tmp dir path in kubectl test.
**What this PR does / why we need it**:
Current case uses hardcoded tmp dir path, and it does not delete tmp dir after test run.
Which means 1. The case could not be run by different users (no permission) 2. /tmp dir keeps growing.
**Which issue this PR fixes**
**Special notes for your reviewer**:
**Release note**:
When volume's status is 'attaching', its attachments will be None,
controllermanager can't get device path and make some failed event.
But it is normal, let's fix it.

Fix XDG-based kubectl plugin dirs
XDGDataPluginLoader messed up its default-value handling for `XDG_DATA_DIRS` and ends up scanning *all of /usr/share* looking for plugins if you don't have that set :-O

Use real proxier inside hollow-proxy but with mocked syscalls
Fixes https://github.com/kubernetes/kubernetes/issues/43701
This should make hollow-proxy better mimic the real kube-proxy in performance.
Maybe next we should have a more realistic implementation even for fake iptables (adding/updating/deleting rules/chains in an table, just not on the real one)? Though I'm not sure how important it is.

rkt: Improve the Garbage Collection
**What this PR does / why we need it**:
This PR improve the garbage collection of files written inside the `/var/lib/kubelet/pods/<pod: id>`
It removes the` finished-<pod: id>` file touched during the `ExecStopPost` of the systemd unit.
It also removes the `/dev/termination-log` file mounted into containers .
The termination-log is used to produce a message from the container and collected by the kubelet when the Pod stops.
Especially for the termination-log, removing theses files will free the associated space used on the filesystem.
**Release note**:
`NONE`

Fix AssertCalls usage for kubelet fake runtimes unit tests
Despite its name, AssertCalls() does not assert anything. It returns an error that should be checked. This was causing false negatives for a handful of unit tests, which are also fixed here.
Tests for the image manager needed to be rearranged in order to accommodate a potentially different sequence of calls each tick because the image puller changes behavior based on prior errors.

orphan when kubectl delete --cascade=false
The default for new objects is to propagate deletes (use GC) when no deleteoptions are passed. In addition, the vast majority of kube objects use this default. Only a few controllers resources (sts, rc, deploy, jobs, rs) orphan by default. This means that when you do `kubectl delete sa/foo --cascade=false` you do *not* orphan. That doesn't fulfill the intent of the command. This explicitly orphans when `--cascade=false` so we don't use GC.

@jwforres I liked this easter egg :)
@kubernetes/sig-cli-bugs we should backport this to 1.6
change import of client-go/api/helper to kubernetes/api/helper
remove unnecessary use of client-go/api.registry
change use of client-go/pkg/util to kubernetes/pkg/util
remove dependency on client-go/pkg/apis/extensions
remove unnecessary invocation of k8s.io/client-go/extension/intsall
change use of k8s.io/client-go/pkg/apis/authentication to v1
