vSphere: set vCenter client UserAgent

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

Setting the client UserAgent makes it easier to identify vCenter sessions
used by the vSphere Cloud Provider.  This is useful to remove sessions that
have leaked, such as when a VCP process goes away without calling Logout().
And to test that VCP properly re-authenticates when a session is removed.

Example use:
``` console
% govc session.ls | grep kubernetes-cloudprovider | awk '{print $1}' | xargs -n1 govc session.rm
```

**Special notes for your reviewer**:

Prior to the change, the session UserAgent is listed as `Go-http-client/1.1`, with the change as `kubernetes-cloudprovider/v1.12.0-...`

Format based on the azure provider client User-Agent: https://github.com/kubernetes/kubernetes/blob/ac99da5e3e0c0df07f12cca153df3baed0b6dd49/pkg/cloudprovider/providers/azure/azure.go#L386-L393

kubeadm: Use separate YAML docs for the kubelet and kube-proxy ComponentConfigs

**What this PR does / why we need it**:
This PR makes kubeadm load the ComponentConfig for the kubelet and kube-proxy from separate YAML documents in the `kubeadm init` config file. This is backwards-compatible with `v1alpha2`. The ComponentConfigs are stored internally in the internal kubeadm `MasterConfiguration` struct, but when marshalling the componentconfigs are written as separate YAML documents.

kubeadm: Start using internal versions for ComponentConfigs in the internal API

**What this PR does / why we need it**:
This PR changes kubeadm to store the internal API versions of the ComponentConfig APIs, in order to in the future be able to read multiple external versions with conversion. It also moves all the ComponentConfigs to a common struct instead of splitting them out in many. This makes it possible to more easily host more ComponentConfigs in the future. In v1alpha3, the ComponentConfigs will later be removed from the external version of the API (see: https://github.com/kubernetes/kubernetes/pull/65787), but for this PR no changes to the external API are made.
