* Fix bug where GetPodsFor(pod) was returning all pods in a namespace
Problem
In lister.GetPodsFor, when the input object was a pod, we would return all the pods in the namespace. I would expect GetPodsFor(pod) to return only one pod - the pod itself.
Cause
The cause of this is that when the object type was pod we were setting the selector to selector = labels.Everything() which gets all the pods in the namespace.
Fix
Special case GetPodsFor(pod) to return the pod itself, rather than looking up pods via labels.
* Modify the Stat endpoint to also return the count of failed pods
* Add comments explaining pod count stats
* Rename total pod count to running pod count
This is to support the service mesh overview page, as I'd like to include an indicator of
failed pods there.
public-api and and tap were both using their own implementations of
the Kubernetes Informer/Lister APIs.
This change factors out all Informer/Lister usage into the Lister
module. This also introduces a new `Lister.GetObjects` method.

The Kubernetes client-go Informer/Lister APIs are implemented in several
parts of the code base.
This change introduces a Lister module, providing Informer/Lister
capability through a simple interface. Once this merges, we can follow
up with moving public-api and tap onto Lister.
