Added RDS provider.

Example Cluster Definition :

Ironfan.cluster 'rds' do
  environment           :_default
  cloud(:rds).security_group(:tests).authorize_ip_range "127.0.0.1/32"
  cloud(:rds).security_group(:tests2).authorize_ec2_group "123456789/systemwide"

  facet :mysql do
    cloud(:rds) do
      password              "abc123"
      username              "root"
      flavor                "db.m1.small"
      size                  5
      port                  3601
    end
  end
end

Huh. I want to be uncomfortable about this, but I'm actually finding little to be uncomfortable about. Definitely needs some further inspection, but I think I like it.

Can we add silverware-style announcements of the underlying DB, saved to the node? That's about the only integration point that I could see missing on a quick and dirty pass through the code. And having those would make cleaning up the various RDS integrations much easier.

Announcements are the end goal. Unfortunately, chef-client never runs on these servers so it will have to be done at launch.

Your example should say use_cloud :rds inside that facet; if there's more than one cloud defined (and cloud :ec2 is usually in the header of the cluster file), Ironfan has to guess at which to use, and guesses wrong without that. Just FYI for docco purposes.
