Absinthe: Quadratic fragment-name uniqueness check

Summary An unauthenticated attacker can stall an Absinthe-backed GraphQL endpoint by submitting a query that contains many fragment definitions. The fragment-name uniqueness validation phase is ON² in the number of fragments, so a single modestly-sized request burns seconds of CPU per worker, and...
