Elixir 1.9

Releases have always been part of the Elixir community thanks to Paul Schoenfelder’s work on Distillery (and EXRM before that). The goal of Elixir releases was to double down on the most important concepts provided by Distillery and provide extensions points for the other bits the community may find important. However, since releases provide runtime configuration and Mix is not included in releases, we ported the API to Elixir.
