Add support for TestingModule to return RuleParams for rules created by the module. Refactor TestingModule to use helpers, and use the helpers to implement a similar TestingSingleton. Use the new functionality to test RuleBuilder's module and singleton rules. Test: none Change-Id: I8348c56ff5086d0c49401f5a00faf7c864e6b6f3
