back port oozie-130 to 2.3 branch
Closes OOZIE-130 build workflow progress information in Oozie
Incorporated review feedback
I'd like to keep this one off 2.3 as it change the client API
yes, client API has been changed (getProgress() added), but why the concern?
It should not affect the exist applications - they wont call this anyway.
