T366837 added the ability to group REST endpoints into modules. This change now introduces the first use of a REST module. The existing endpoints remain accessible at their original paths, and mocha tests are run against both old and new paths. Bug: T370430 Change-Id: I83a5cdbdd359e4d3e5f70dd3930783616b556738
