Our current unicorn task wasn't working in some cases. We also had a
version in the `capistrano` branch, which was the one we recommended.
However, that version assumed RVM, a certain ruby version and a certain
deploy folder were used. This version uses `bundle exec` and variables
like `release_path`, so it does not depend on any specific
configuration.
Even if we're replacing unicorn with puma, I wanted to make this change
in case we need it as a reference in the future.
We are using a simple unicorn.rb file in the Installer, which requires a different way of restarting the server
This task is still a little limited and hackish but it does the job for now 😌
We are killing any existing unicorn process and starting unicorn. It checks for existing processes in both the standard consul folder and in the capistrano `current` folder, and skipping any exception if unicorn was not running.
