| Start delayed_job worker daemon. Requires passing start|stop|restart|reload|run|zap|status | |
| to rake via `rake jobs:daemon[start]`. To pass arguments to Delayed::Command, call rake | |
| like `rake jobs:daemon["--queue=something start"]` (Note the quotes wrapping the arguments!). | |
| Available flags are: queues queue min_priority max_priority number_of_workers pid-dir | |

| task :daemon, [:argv] => :environment do |t, args| | |
| # If we have anything in args.extras we need to combined it with args[:argv] | |
| # This lets us handle comma-separated values for --queues. | |
| fake_argv = [args[:argv], args.extras].flatten.compact.join(',') | |
