#17744
This change implements a new query parameter on `/teams/%d/policies` to
merge inherited policies into the policies array instead of listing them
separately. The frontend will key off the existing `team_id` field to
mark policies as "inherited" in theUI.
I opted for an additive approach in adding a datastore method rather
than modifying the existing ListTeamPolicies to avoid a large test
refactor.
