Installs all recommended packages

[Bitblade]

On Debian, the default is to install all recommended packages with the main package. Unfortunately, collectd has an absurd amount of recommended packages.

Since apt installs these recommended packages recursively, this role installs about 205MB of 'recommended' packages, including mysql-common, openjdk and even several X11 packages.

Suggest using the install_recommends option on the apt task.
