Justin Santa Barbara 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).

Justin Santa Barbara 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.

Aaron Crickenberger 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.
