kubeadm: Remove dependency on pkg/client/clientset_generated/internalclientset
**What this PR does / why we need it**:
This PR removes dependency in kubeadm on `pkg/client/clientset_generated/internalclientset` and blacklists it in `.import-restrictions`.
The above package is pulled in transitively by the usage of the following:
- [GetFlagString](a481f4bbe8/cmd/kubeadm/app/cmd/version.go (L63)) from `k8s.io/kubernetes/pkg/kubectl/cmd/util`
- [LeaseEndpointReconcilerType](a481f4bbe8/cmd/kubeadm/app/phases/controlplane/manifests.go (L205)) from `k8s.io/kubernetes/pkg/master/reconcilers`
Dropping the unneeded dependencies from the build shaves off 4-5MB from the amd64 executable and reduces the dependency hell in kubeadm.

Adds a mechanism in vSphere Cloud Provider to get credentials from Kubernetes secrets
**What this PR does / why we need it**:
Currently, vCenter credentials are stored in plain text in vsphere.conf. This PR adds a mechanism in vSphere Cloud Provider to get vCenter credentials from Kubernetes secrets.
**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
Fixes #
**Special notes for your reviewer**:
Internally review here: https://github.com/vmware/kubernetes/pull/484
**Workflow:**
1. Create vsphere.conf file with ```secret-name``` and ```secret-namespace```.
```
[Global]
insecure-flag = 1
secret-name = "vcconf"
secret-namespace = "kube-system"
[VirtualCenter "10.160.45.119"]
port = 443
datacenters = k8s-dc-1
[Workspace]
server = 10.160.45.119
datacenter = k8s-dc-1
default-datastore = sharedVMFS-0
folder = Discovered virtual machine
```
2. Launch Kubernetes cluster with vSphere Cloud Provider Configured.
3. Create secret with vCenter credentials.
a. Create base64 encoding for username and password:
username:
```
> echo -n 'admin' | base64
YWRtaW4=
```
password:
```
> echo -n 'vsphere' | base64
dnNwaGVyZQ==
```
b. kubectl create -f vccredentials.yaml
```
#vccredentials.yaml
apiVersion: v1
kind: Secret
metadata:
name: vcconf
type: Opaque
data:
10.192.44.199.username: YWRtaW4=
10.192.44.199.password: dnNwaGVyZQ==
```
4. vSphere Cloud Provider can be used now.
**Note:**
Secrets info can be provided with both (old and new) vSphere Cloud provider configuration formats.
**Tests Done:**
- [x] vSphere Cloud Provider unit test.
- [x] Volume lifecyle with Username and Password in vsphere.conf (for backward compability)
- [x] Volume lifecyle with secrets information in vsphere.conf.
- [x] Update secrets workflow
**Release note**:
```release-note
Adds a mechanism in vSphere Cloud Provider to get credentials from Kubernetes secrets

kubeadm uses LeaseEndpointReconcilerType as import from
k8s.io/kubernetes/pkg/master/reconcilers. However, this pull a huge
load of extra dependencies (among which
pkg/client/clientset_generated/internalclientset). The solution is
to copy this string constant locally in kubeadm.

Adding details to Conformance Tests using RFC 2119 standards.
This PR is part of the conformance documentation. This is to provide more formal specification using RFC 2119 keywords to describe the test so that who ever is running conformance tests do not have to go through the code to understand why and what is tested.
The documentation information added here into each of the tests eventually result into a document which is currently checked in at location https://github.com/cncf/k8s-conformance/blob/master/docs/KubeConformance-1.9.md
I would like to have this PR reviewed for v1.10 as I consider it important to strengthen the conformance documents.

Add InstallPathHandler which allows for more then one path to be associated with health checking.
Currently it is only possible to have one group of checks which must all pass for the handler to report success.
Allowing multiple paths for these checks allows use of the same machinery for other kinds of checks, i.e. readiness.

start splitting polymorphic functions out of the factory
the polymorphic behavior in `kubectl` has been gathered in the factory, but with the new kubeconfigflags and interfaces, it can actually be re-written as a set of helper calls.
These functions are special. They are indications of areas of flexibility that we eventually need to build generically. In addition, unit tests make heavy use of injection. For these reasons we aren't inlining them. Instead we'll extra to a polymorphic package and have them as assignable functions for mocking.
Individual commands should support injection for cleaner mocking and we'll be able to use the package to hunt internal dependencies.
