Our evergreen test suite is clogged by warnings of map_reduce being deprecated. With MONGOID-4998 the Mongoid::Warnings module can be used to cache warnings so they only happen once: 
W, 2022-07-08T18:42:12.394985 #2297 WARN – : MONGODB | The map_reduce operation is deprecated, please use the aggregation pipeline instead
W, 2022-07-08T18:43:28.353863 #2297 WARN – : #as_json :compact option is deprecated. Please call #compact on the returned Hash object instead.
- has to be done after
