🎩 What? Why?

This PR will improve the way the default application is created via the decidim generator.
The goal is to set a full-featured application ready to run and configurable, at least with the default adaptations (such as the map provider), entirely via ENV variables.

This changes will make the default Decidim application fully compliant with the 12 Factor principles and will facilitate the later introduction of better scripts or containers fully prepared to easily deploy Decidim with minimal customization.

Notes
Marked with ⛔ are configuration options that require additional code efforts to make it work (such as create a service class). We will NOT set up env vars for these options at the moment. In the future, if some default providers are added we might add these as env vars options as well.

• Omniauth defaults & tests
• Complete default secrets.yml defaults with env vars
• Full SMTP config

• Application mailer sender
