Abu Kashem 50cce843c9 Take into account latency incurred in server filters 
apiserver_request_duration_seconds does not take into account the
time a request spends in the server filters. If a filter takes longer
then the latency incurred will not be reflected in the apiserver
latency metrics.

For example, the amount of time a request spends in priority and
fairness machineries or in shuffle queues will not be accounted for.

- Add a server filter that attaches request received timestamp to the
request context very early in in the handler chain (as soon as
net/http hands over control to us).
- Use the above received timestamp in the apiserver latency metrics
apiserver_request_duration_seconds.
- Use the above received timestamp in the audit layer to set
RequestReceivedTimestamp.

apiserver

Generic library for building a Kubernetes aggregated API server.

Purpose

This library contains code to create Kubernetes aggregation server complete with delegated authentication and authorization, kubectl compatible discovery information, optional admission chain, and versioned types. It's first consumers are k8s.io/kubernetes, k8s.io/kube-aggregator, and github.com/kubernetes-incubator/service-catalog.

Compatibility

There are NO compatibility guarantees for this repository, yet. It is in direct support of Kubernetes, so branches will track Kubernetes and be compatible with that repo. As we more cleanly separate the layers, we will review the compatibility guarantee. We have a goal to make this easier to use in the future.

Where does it come from?

apiserver is synced from https://github.com/kubernetes/kubernetes/blob/master/staging/src/k8s.io/apiserver. Code changes are made in that location, merged into k8s.io/kubernetes and later synced here.

Things you should NOT do

  1. Directly modify any files under pkg in this repo. Those are driven from k8s.io/kubernetes/staging/src/k8s.io/apiserver.
  2. Expect compatibility. This repo is changing quickly in direct support of Kubernetes and the API isn't yet stable enough for API guarantees.
