Rails::Application::Configuration#load_database_yaml

Loads the database YAML without evaluating ERB.  People seem to
write ERB that makes the database configuration depend on
Rails configuration.  But we want Rails configuration (specifically
`rake` and `rails` tasks) to be generated based on information in
the database yaml, so we need a method that loads the database
yaml *without* the context of the Rails application.
