feat: Implemented configurable RAILS_ENV

Before this change, RAILS_ENV was hardcoded to `production`. This was not a best solution, since
many different environments may be introduced to AWS stack (`staging`, `beta` etc.). To solve this,
the `app['framework']['rails_env']` configuration parameter is introduced, which serves exactly for
that purpose.

Resolves #34
