09a2e49a94 kubeadm: fix RequiredIPVSKernelModulesAvailable warning message
RequiredIPVSKernelModulesAvailable warning confuses users suggesting
that the IPVS proxier will not be used, which is not always the case.

Made the warning message less confusing:

        [WARNING RequiredIPVSKernelModulesAvailable]:
The IPVS proxier may not be used because the following required kernel
modules are not loaded: [ip_vs_rr ip_vs_wrr ip_vs_sh]
or no builtin kernel ipvs support was found: map[ip_vs_wrr:{}
ip_vs_sh:{} nf_conntrack_ipv4:{} ip_vs:{} ip_vs_rr:{}].
However, these modules may be loaded automatically by kube-proxy for you
if they are available on your system.

To verify IPVS support:

   Run "lsmod | grep 'ip_vs\|nf_conntrack'" and verify each of the above
modules are listed.

If they are not listed, you can use the following methods to load them:

1. For each missing module run 'modprobe $modulename' (e.g., 'modprobe
ip_vs', 'modprobe ip_vs_rr', ...)
2. If 'modprobe $modulename' returns an error, you will need to install
the missing module support for your kernel.

Fixes: kubernetes/kubeadm#975

Move from glog to klog
- 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
