Adjust templates for Juno.
Merge pull request #214 from toabctl/juno-config

Port to Juno config
Fixed permissions for various files
Fixed raw/custom proposal links
Cleaned crowbar config and added travis image to readme

The goal is to remove the package requirements from the crowbar
configuration as the dev tool and all the dependencies for building isos
on the dell way is not maintained anymore and move the packaging to obs
instead.
Added ruby 2.1.0 to travis config
