8ac484793d Comment out calls to httptest.Server.Close() to work around 
https://github.com/golang/go/issues/12262 . See #19254 for
more details. This change should be reverted when we upgrade
to Go 1.6.

f9a6ac077e Ubernetes Lite: Volumes can dictate zone scheduling 
For AWS EBS, a volume can only be attached to a node in the same AZ.
The scheduler must therefore detect if a volume is being attached to a
pod, and ensure that the pod is scheduled on a node in the same AZ as
the volume.

So that the scheduler need not query the cloud provider every time, and
to support decoupled operation (e.g. bare metal) we tag the volume with
our placement labels.  This is done automatically by means of an
admission controller on AWS when a PersistentVolume is created backed by
an EBS volume.

Support for tagging GCE PVs will follow.

Pods that specify a volume directly (i.e. without using a
PersistentVolumeClaim) will not currently be scheduled correctly (i.e.
they will be scheduled without zone-awareness).

d9f3607292 Implement multi-scheduler: 
1. Name default scheduler with name `kube-scheduler`
2. The default scheduler only schedules the pods meeting the following condition:
	- the pod has no annotation "scheduler.alpha.kubernetes.io/name: <scheduler-name>"
	- the pod has annotation "scheduler.alpha.kubernetes.io/name: kube-scheduler"

7f4f754106 scheduler: calculate priority in parallel. 
To improve the throughput of current scheduler, we can do
a simple optimization by calcluating priorities in parallel.

This doubles the throughput of density test, which has the default
config with 3 priority funcs (the spreading one does not actually
consume any computation time). It matches the expectation.

6aa16c744b When scheduling, spread between zones if labeled 
We already spread across nodes; we modify this spreading preference to
spread across zones when nodes are labeled with zone information.

fad1968023 Adjust V level for scheduler messages 
The "Combined requested resources" message becomes excessive as
the cluster fills up, drop it down to V(2)

Put an explicit V(2) on the only other scheduler Infof call that didn't
have V specified already.
