Track object modifications in fake clientset
Fake clientset is used by unit tests extensively but it has some
shortcomings:
- no filtering on namespace and name: tests that want to test objects in
multiple namespaces end up getting all objects from this clientset,
as it doesn't perform any filtering based on name and namespace;
- updates and deletes don't modify the clientset state, so some tests
can get unexpected results if they modify/delete objects using the
clientset;
- it's possible to insert multiple objects with the same
kind/name/namespace, this leads to confusing behavior, as retrieval is
based on the insertion order, but anchors on the last added object as
long as no more objects are added.
This change changes core.ObjectRetriever implementation to track object
adds, updates and deletes.
Some unit tests were depending on the previous (and somewhat incorrect)
behavior. These are fixed in the following few commits.

Volume manager must verify containers terminated before deleting for ungracefully terminated pods
A pod is removed from volume manager (triggering unmount) when it is deleted from the kubelet pod manager. Kubelet deletes the pod from pod manager as soon as it receives a delete pod request. As long as the graceful termination period is non-zero, this happens after kubelet has terminated all containers for the pod. However, when graceful termination period for a pod is set to zero, the volume is deleted from pod manager *before* its containers are terminated.
This can result in volumes getting unmounted from a pod before all containers have exited when graceful termination is set to zero.
This PR prevents that from happening by only deleting a volume from volume manager once it is deleted from the pod manager AND the kubelet containerRuntime status indicates all containers for the pod have exited. Because we do not want to call containerRuntime too frequently, we introduce a delay in the `findAndRemoveDeletedPods()` method to prevent it from executing more frequently than every two seconds.
