Relocate and Adjust UAT line in file_defs

[tjacovich]

This line is incorrect.

ADSDataPipeline/adsdata/file_defs.py

Line 81 in 4b31e77

data_files['uat'] = {'path': 'links/uat/all.links', 'default_value': [], 'multiline': True}

needs to be located below

ADSDataPipeline/adsdata/file_defs.py

Line 86 in 4b31e77

env_name = config.get('ENVIRONMENT', 'back-dev')

And be of the form:

data_files['uat'] = {'path': 'links/uat/uat.list.'+str(env_name), 'default_value': [], 'multiline': True}
