[Rdo-list] [OFI] ER diagram

[Petr Chalupa]

Hi,

I wanted to understand the current model better so I've generated ER 
diagram from Scott's PR https://github.com/theforeman/staypuft/pull/12.

see http://projects.theforeman.org/projects/ofi/wiki/DB_Model

How to: add `gem 'rails-erd'` and execute `rake erd 
only='Staypuft::Deployment,Staypuft::DeploymentHostgroup,Staypuft::HostgroupRole,Staypuft::Layout,Staypuft::LayoutRole,Staypuft::Role,Staypuft::RoleClass,Staypuft::RoleService,Staypuft::Service,Staypuft::ServiceClass,Hostgroup,Puppetclass' 
attributes='foreign_keys,content' orientation=vertical filetype=dot`
then `dot -Tsvg erd.dot > erd.svg`
