Automated changes git author

[Thomas Weise]

Hi,

For changes made by scripts, there has been an undocumented convention to
use the following author information (example):

commit 763d14fca6b84fdda1b6853235e5d4b71ca87fca
Author: CI Support <jenk...@datatorrent.com>
Date:   Mon Sep 26 20:36:22 2016 -0700

    Fix trailing whitespace.

I would suggest we discontinue use of jenk...@datatorrent.com and start
using dev@apex.apache.org instead?

Thanks,
Thomas
