Verbose logging

[moqmar]

I'm using Horust to start Apache2, which is by itself a very quiet service - even with the "debug" log level, it doesn't show when it started up. It would be great if there was a -v flag to Horust that would cause it to output messages like the following ones:

• Started service "apache2"
• Service "apache2" is now healthy
• Service "php-fpm" failed with strategy "shutdown", stopping all services
• Stopped service apache2

This would make the log output way more useful, as also information the services processes themselves can't know would be logged.
