Since docker 18.09, the ServerVersion field format changed: the `-ce`
or `-ee` suffix disappeared:
- docker 18.06: `18.06.1-ce`
- docker 18.09: `18.09.0`
This was not expected by the docker_validator version regexp, which
assumed newer docker versions ended with `-[a-z]{2}`.
This made the validator return an error, whereas we expect it to
return only a warning (by recognizing it as a newer but not yet
supported docker version).
This commit relax the version regexp to also recognize `18.09.0`.
The docker validator now returns a warning, as tested.
- Move from the old github.com/golang/glog to k8s.io/klog
- klog as explicit InitFlags() so we add them as necessary
- we update the other repositories that we vendor that made a similar
change from glog to klog
* github.com/kubernetes/repo-infra
* k8s.io/gengo/
* k8s.io/kube-openapi/
* github.com/google/cadvisor
- Entirely remove all references to glog
- Fix some tests by explicit InitFlags in their init() methods

Up until now UnifiedControlPlaneImage existed as a string value as part of the
ClusterConfiguration. This provided an override for the Kubernetes core
component images with a single custom image. It is mostly used to override the
control plane images with the hyperkube image. This saves both bandwith and
disk space on the control plane nodes.
Unfortunately, this specified an entire image string (complete with its prefix,
image name and tag). This disables upgrades of setups that use hyperkube.
Therefore, to enable upgrades on hyperkube setups and to make configuration
more convenient, the UnifiedControlPlaneImage option is replaced with a boolean
option, called UseHyperKubeImage. If set to true, this option replaces the
image name of any Kubernetes core components with hyperkube, thus allowing for
upgrades and respecting the image repository and version, specified in the
ClusterConfiguration.

Removed slelfhosting upgrade ability
Added warning message to self hosted pivot
added certs in secrets flag to new selfhosting comand
Until now the control plane timeout was fixed to 4 minutes and users did not
have the ability to change it. This commit allows that timeout to be configured
via the new `timeoutForControlPlane` option in the API server config (itself a
member of the ClusterConfiguration).
The default timeout is still 4 minutes.
