first throw create request api

first throw create request api
still open to discussions:

• do we need sorting logic for the request task (e.g. group_create, group_modify:add members -> access -> group_modify:remove members) in analogy to FWRequest from Modelling?
• how to handle fields currently just written to AdditionalInfo: GroupId, RequestContactName, RequestContactId, RequestorName, RequestorId, TimeObjectId
