Subject: [PATCH] Enabled systemd socket activation (PR #942)

With this [configuration](https://github.com/puma/puma/blob/master/docs/systemd.md) puma automatically binds to all systemd activated sockets. With socket activation systemd opens the listening socket(s) in advance and provides them to the Puma master process on startup. This keeps listening sockets open across puma restarts and achieves graceful restarts.
