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

pkg/proxy: only set sysctl if not already set 
This will allow for kube-proxy to be run without `privileged` and
with only adding the capability `NET_ADMIN`.

Patrice Ferlet 439a03136f Check sysfs Type instead of Device 
Some distribution, or installation use "none" device to mount sysfs (eg. Scaleway VPS). We should check the mount type instead of device.

Fix #37183

Kubernetes Submit Queue 973fa6b334 Merge pull request #35821 from vishh/gci-mounter-scope 
Automatic merge from submit-queue

[Kubelet] Use the custom mounter script for Nfs and Glusterfs only

This patch reduces the scope for the containerized mounter to NFS and GlusterFS on GCE + GCI clusters

This patch also enabled the containerized mounter on GCI nodes

Shepherding multiple PRs through the submit queue is painful. Hence I combined them into this PR. Please review each commit individually.

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

Fix Kube-proxy `conntrack.go` **TODO** [here](https://github.com/kubernetes/kubernetes/blob/master/cmd/kube-proxy/app/conntrack.go#L56). This PR consists of two parts:

* Generify kube-proxy `realConntracker.SetMax(int)` 

That is, change

`ioutil.WriteFile("/sys/module/nf_conntrack/parameters/hashsize", []byte(strconv.Itoa(max/4)), 0640)` 

to

`sysctl.New().WriteValue("/sys/module/nf_conntrack/parameters/hashsize", max/4)`

* Refactor `sysctl.SetSysctl()` and `sysctl.GetSysctl()` to `WriteValue(path string, value string) error` and `GetValue(path value) (error, string)`

Jing Xu 34ef93aa0c Add mounterPath to mounter interface 
In order to be able to use new mounter library, this PR adds the
mounterPath flag to kubelet which passes the flag to the mount
interface. If flag is empty, mount uses default mount path.

Tim Hockin da0ac31182 Set conntrack params in kube-proxy 
Add flags to control max connections (set to 256k vs 64k default) and TCP
established timeout (set to 1 day vs 5 day default).  Flags can be set to 0 to
mean "don't change it".

This is only set at startup, and not wrapped in a rectifier loop.

Tested manually.
