Add --feature-gate flags to kubeadm
**What this PR does / why we need it**:
Adds `--feature-gates` in similar manner to other `cmd` binaries
**Which issue this PR fixes**
https://github.com/kubernetes/kubeadm/issues/323
**Special notes for your reviewer**:
This results in a lot of probably unnecessary feature flags. I'm guessing a lot of kubeadm users will be confused when they see:
```
Flags:
--feature-gates mapStringBool A set of key=value pairs that describe feature gates for alpha/experimental features. Options are:
APIResponseCompression=true|false (ALPHA - default=false)
Accelerators=true|false (ALPHA - default=false)
AdvancedAuditing=true|false (ALPHA - default=false)
AllAlpha=true|false (ALPHA - default=false)
AllowExtTrafficLocalEndpoints=true|false (default=true)
AppArmor=true|false (BETA - default=true)
DebugContainers=true|false (ALPHA - default=false)
DynamicKubeletConfig=true|false (ALPHA - default=false)
DynamicVolumeProvisioning=true|false (ALPHA - default=true)
ExperimentalCriticalPodAnnotation=true|false (ALPHA - default=false)
ExperimentalHostUserNamespaceDefaulting=true|false (BETA - default=false)
LocalStorageCapacityIsolation=true|false (ALPHA - default=false)
PersistentLocalVolumes=true|false (ALPHA - default=false)
PodPriority=true|false (ALPHA - default=false)
RotateKubeletClientCertificate=true|false (ALPHA - default=false)
RotateKubeletServerCertificate=true|false (ALPHA - default=false)
StreamingProxyRedirects=true|false (BETA - default=true)
TaintBasedEvictions=true|false (ALPHA - default=false)
-h, --help help for kubeadm
```
However the feature flags used in the core pkg is global, so I don't think it can be overriden. So we have a few options:
1. Allow these flags for kubeadm
2. Refactor feature pkg to allow granular features
3. Roll our own feature gating for kubeadm

kubeadm: Start to remove old envparams
**What this PR does / why we need it**:
Historically, the envparams feature was used as a way to easily debug `kubeadm` while developing it in the v1.3-v1.4 timeframe. Since then some parameters have been hanging around and not being moved into the API as they should have.
Note: This is a temporary step; moving things into the API. Still, the API is gonna change, this is not the end state. But this is better than keeping the envparams.
I'm gonna deal with `KubernetesDir` in the next PR.

Allow to specify a node-name instead of relaying in `os.Hostname()`
This is useful where kubelet use the name given by the cloud-provider to
register the node.

Remove old node role label that is not used by kubeadm
**What this PR does / why we need it**:
This label hasn't been used by kubeadm since v1.5.
v1.5 support was dropped when v1.6 arrived due to a potential security flaw and the earlier alpha status.
So this label hasn't been used for around three months.
It makes sense to remove it in time for v1.8, could already have been done for v1.7

kubeadm: If `--config` is set, don't allow any other option as it won't have effect
If use config in kubeadm init, cann't get other values from other arguments.
`kubeadm init --config=../kubeadm.config --token 447ad3.96cda76e3206fca0 --apiserver-bind-port 6445`
So I think we need to allow get values from command and is prior than cofig file.

Prepare for move zz_generated_deepcopy.go to k8s.io/api
This is in preparation to move deep copies to with the types to the types repo (see https://github.com/kubernetes/gengo/pull/47#issuecomment-296855818). The init() function is referring the `SchemeBuilder` defined in the register.go in the same packge, so we need to revert the dependency.
This PR depends on https://github.com/kubernetes/gengo/pull/49, otherwise verification will fail.

Allow configurable etcd options
**What this PR does / why we need it**:
Allows users to set the `--listen-client-urls` and `--advertise-client-urls` flags on etcd binaries for clusters set up with kubeadm.
**Which issue this PR fixes**:
As far as I can tell right now, other nodes in a cluster set up with kubeadm cannot communicate with the etcd static pod running on the master. This is needed in order to set up calico/canal SDN which needs access to a publicly addressable IPv4 _before_ the overlay network and inter-cluster subnet is created.
Addresses https://github.com/kubernetes/features/issues/138 and https://github.com/kubernetes/features/issues/11.
**Release note**:
```release-note
Users can now specify listen and advertise URLs for etcd in a kubeadm cluster

kubeadm: Demote --self-hosted to master config file.
**What this PR does / why we need it**:
kubeadm init --self-hosted was meant to be a short lived hack to enable self-hosted deployments until we're ready to make them the default. Rather than shipping this in 1.6 (for the first time) we will move this to the config file as it is presently only an advanced feature, leaving us with more well supported ways to remove it in the future.

add sample fuzzing tests
Make fuzzing tests as simple as possible from both the API installer and the scheme, so its easy to add for api groups and so that I can build a scheme and then make sure I got it right.

Some imports dont exist yet (or so it seems) in client-go (examples
being:
- "k8s.io/kubernetes/pkg/api/validation"
- "k8s.io/kubernetes/pkg/util/initsystem"
- "k8s.io/kubernetes/pkg/util/node"
one change in kubelet to import to client-go
