[TEZ-3369][WIP] Fixing Tez's DAGClients to work with Cascading
Adding a few APIs to Tez to help Cascading break its dependency on an
internal implementation and still get some of the data it needs.
Added APIs:
```
DAGInformation getDAGInformation()
TaskInformation getTaskInformation(String vertexID, String taskID)
List<TaskInformation> getTaskInformation(String vertexID, @Nullable String
startTaskID, int limit)
```
Putting this PR out as a WIP to get some feedback on the APIs and the data
they return.
I'm still working through cleaning up the code, fixing some todos and
testing more.
