Han Kang 4a680138c0 Fix double counting issue for request metrics on timeout. 
Currently we record request metrics during the normal request flow and
we also manually invoke `Record` in the timeout handler to record
timeouts. This means that we effectively double count whenever we
timeout. This PR renames the `Record` function to `RecordRequestError`
to more accurately reflect the intended side-effect of the function
call.

Clayton Coleman 72566fea6c Replace HTTP compression with an inline handler 
The previous HTTP compression implementation functioned as a filter, which
required it to deal with a number of special cases that complicated the
implementation.

Instead, when we write an API object to a response, handle only that one
case. This will allow a more limited implementation that does not impact
other code flows.

Also, to prevent excessive CPU use on small objects, compression is
disabled on responses smaller than 128Kb in size.

Davanum Srinivas e2884e1186 Revert "Generate Stack Traces for http response with status code zero" 
Does not help with the bug investigation. the http server is designed to
panic when the http status code is `0`.

Davanum Srinivas 2b1eeee742 Generate Stack Traces for http response with status code zero 
When we spit out a http reponse with a `0` http status code we
should log a trace back so we can easily find where things went wrong.

Davanum Srinivas 2710b17b80 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
