The services dropdown will be decoupled from the navigation files. Its entries will be explicitly defined within the Frontend resource.

Similar to navigation files, individual entries will be injected into a template. Templa is quite simpler than for navigation. It is just a list named tabs. Items in them will be sorted alphabetically which is different from today.

Spec for a "dropdown tile and template" can be found here: https://docs.google.com/document/d/1P_F9P06t4SbhHOxrqOzz5ORQjdzzfjC311sLmsyWBkM/edit#heading=h.fmiu84z4j56l

The Frontend resource should receive a new optional attribute ServiceEntries. It should be an array of ServiceTile definitions.
