CPANTesters deploy with Rex

[preaction]

We should start automating the configuration and deploying of the CPANTesters server(s) with Rex (http://rexify.org).

We should break the deploy up into three parts: database, backend (ETL processes, reports mailer, generators), and web app. In the future, we want to deploy these parts to different servers.

We need a single repository to keep our configuration files, deployment scripts, crontabs, and any other automation for deploying and updating the CPANTesters servers.

This should be one of our first steps before continuing on other sysadmin tasks.

This has been started in the cpantesters-deploy repository. A logrotate config has been added. The next steps should be:

• Ensure the required system packages are installed
• Ensure the CPANTesters Perl prereqs are installed
• Deploy the CPANTesters software
• Deploy the crontabs
