This commit contains only changes generated by the build process.
Nothing here was manually changed.
Changes made to:

currently sub phases cannot have custom arg validation and container commands can have args.
This removes phase container commands from taking args and enables custom args on the leaf phases
* fix duplicated imports of api/core/v1
* fix duplicated imports of client-go/kubernetes
* fix duplicated imports of rest code
* change import name to more reasonable
During the upgrade process, `kubeadm` will take the current
`ClusterConfiguration`, update the `KubernetesVersion` to the latest
version, and call to `UploadConfiguration`.
This change makes sure that when the mutation happens, not only the
`ClusterStatus` is mutated, but the `ClusterConfiguration` object
inside the `kubeadm-config` ConfigMap as well; it will contain the
new `KubernetesVersion`.
There are a couple of problems with regards to the `omitempty` in v1beta1:
- It is not applied to certain fields. This makes emitting YAML configuration
files in v1beta1 config format verbose by both kubeadm and third party Go
lang tools. Certain fields, that were never given an explicit value would
show up in the marshalled YAML document. This can cause confusion and even
misconfiguration.
- It can be used in inappropriate places. In this case it's used for fields,
that need to be always serialized. The only one such field at the moment is
`NodeRegistrationOptions.Taints`. If the `Taints` field is nil, then it's
defaulted to a slice containing a single control plane node taint. If it's
an empty slice, no taints are applied, thus, the cluster behaves differently.
With that in mind, a Go program, that uses v1beta1 with `omitempty` on the
`Taints` field has no way to specify an explicit empty slice of taints, as
this would get lost after marshalling to YAML.
To fix these issues the following is done in this change:
- A whole bunch of additional omitemptys are placed at many fields in v1beta2.
- `omitempty` is removed from `NodeRegistrationOptions.Taints`
- A test, that verifies the ability to specify empty slice value for `Taints`
is included.

This change introduces config fields to the v1beta2 format, that allow
certificate key to be specified in the config file. This certificate key is a
hex encoded AES key, that is used to encrypt certificates and keys, needed for
secondary control plane nodes to join. The same key is used for the decryption
during control plane join.
It is important to note, that this key is never uploaded to the cluster. It can
only be specified on either command line or the config file.
The new fields can be used like so:
---
apiVersion: kubeadm.k8s.io/v1beta2
kind: InitConfiguration
certificateKey: "yourSecretHere"
---
apiVersion: kubeadm.k8s.io/v1beta2
kind: JoinConfiguration
controlPlane:
certificateKey: "yourSecretHere"
---

Even though CreateServiceAccountKeyAndPublicKeyFiles() function is
an interface function it's not unittested. Instead it wraps a couple
of internal functions which are used only inside CreateServiceAccountKeyAndPublicKeyFiles()
and those internal functions are tested.
Rewrite the function to do only what it's intended to do and add unit
tests for it.
These are based on recommendation from
[staticcheck](http://staticcheck.io/).
- Remove unused struct fields
- Remove unused function
- Remove unused variables
- Remove unused constants.
- Miscellaneous cleanups
