fn: paused and evicted container stats (#1209)

Browse Source 
* fn: paused and evicted container stats

With this change, now stats reports paused state
as well as incidents of container exit due to evictions.

* fn: update/document state transitions in state tracker

There's no case of a transition moving from done to waiting. This
must be deprecated behavior.
