Refactor logging to capture Target hierarchy

Instead of creating a fixed number of targets, we now pass an ArrayList
of targets to. Any class implementing
LogContainerProviders#fillInLogContainerData can setup it's own target
and add it to the ArrayList, It can also pass the ArrayList to other
LogContainerProvider to capture full Target hierarchy.
