Create script to install configuration in Heroku

[guidomb]

It would be nice to be able to setup a Heroku app using a local configuration. For example if we have a local file .amazon.yml with the Amazon Web Services credentials

access_key: 1619472940712347103affb9180
secret_access_key: 091847812987129761381239871238129873

by executing something like

appcfg setup heroku -a myapp

This command should automatically export all the configuration defined in app_configuration and export it to Heroku env variables like if you run

heroku config:set AMAZON_ACCESS_KEY=1619472940712347103affb9180 AMAZON_SECRET_ACCESS_KEY=091847812987129761381239871238129873 -a myapp
