The Bulk api retrieval returns all defined types or filtered types by name, type and supertype. With the addition of the service type among the basic attributes of the Atlas types it is necessary to have the possibility to search also for service type through a http request of the type:
http://host:port/api/atlas/V2/types/typedefs?serviceType = requested-service-type
to search only for types related to a specific service type.
This pull request solves this problem
