Review request for samza.


Repository: samza


Description
-------

As a part of the refactoring we separate out Samza specific state and Yarn specific state. As a result, the class SamzaAppState is moved from samza-yarn to samza-core.
The variables in the old SamzaAppState are now split into 
i) Refactored SamzaAppState (in samza core)
ii)YarnAppState (in samza yarn)
Hence, we will need to change the references to SamzaAppState in all the UI scala template classes to work with the newer refactoring. This RB creates a scalatev2 directory that will include the refactored templates.

This RB depends on RB:44920 

Review tools does not support a way to upload a diff against some already existing change-list. Hence, this RB is deceptively large.
