Until this point, the schema/queries that comprised a user's dashboard
were hardcoded into the rest-api. This change removes them from that
file and adds them back to the dashboard-view as properties.
This work is being done as part of addressing Issue 5555, with the goal
of being generic enough to be reused when custom dashboards in PG are
implemented.
