Configure Capistrano to use Puma as a daemon
Configure Capistrano to use Puma as a daemon

Since Puma 5.x will remove support for running Puma as a daemon,
capistrano-puma requires defining whether we want to run Puma as a
daemon (as we've been doing so far with Puma 4.x) or to uses systemd.

We'll change this code to uses systemd when upgrading to Puma 5.x.
