Subject: [PATCH] Update config_version to use a script that does not require
 git

The config_version now uses a script that will do one of two
things:

1. call config_version.rb which uses rugged to find the information
about the latest commit if PE is on version 2015.2 or newer

2. make a call to git if the PE version is less than 2015.2
