9f44c72ba9 AWS: findInstancesByNodeNames should not make O(N) API calls 
findInstancesByNodeNames was a simple loop around
findInstanceByNodeName, which made an EC2 API call for each call.

We've had trouble with this sort of behaviour hitting EC2 rate limits on
bigger clusters (e.g. #11979).

Instead, change this method to fetch _all_ the tagged EC2 instances, and
then loop through the local results.  This is one API call (modulo
paging).

We are currently only using findInstancesByNodeNames for the load
balancer, where we attach every node, so we were fetching all but one of
the instances anyway.

Issue #11979

0586d866de AWS: Eliminate assumptions about all load-balancer ports matching 
It costs us basically nothing to just check all the ports, and
protects us against future changes to the controller.

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).

1b7445a6e2 Use SSD as default volume type. 
General purpose SSD ('gp2') volume type is just slighly more expensive than
Magnetic ('standard' / default in AWS), while the performance gain is pretty
significant.

So far, the volumes were created only during testing, where the extra cost
won't make any difference. In future, we plan to introduce QoS classes, where
users could choose SSD/Magnetic depending on their use cases.

'gp2' is just the default volume type for (hopefuly) short period before these
QoS classes are implemented.

700d92c2a8 AWS: Use GiB as units for disk sizes. 
From some reason, MiBs were used for public functions and AWS cloud provider
recalculated them to GiB. Let's expose what AWS really supports and don't hide
real allocation units.
