 A Cloud SQL (a cloud version of MySQL) database is used to keep information on
 Skia git revisions and their corresponding annotations. The database will be
 updated when users add/edit/delete annotations via the dashboard UI.

 But sysv init only handles starting and stopping a program once, so we use
 Monit to monitor the application and restart it if it crashes. The config
 is in:
 
     /etc/monit/conf.d/perf
 
 Installation
