Puppet Module for EarlyOOM

This puppet module:

• Installs earlyoom package
• Configures /etc/default/earlyoom
• Controls the service earlyoom

The Early OOM Daemon checks the amount of available memory and free swap up to 10 times a second (less often if there is a lot of free memory). By default if both are below 10%, it will kill the largest process (highest oom_score). The percentage value is configurable via command line arguments.
