Added a new service defined as data, whose purpose is to
receive requests, process data operations such as copying,
migration, backup, and send back the response after operation
has been completed.
In this patch the service has no methods, it is empty, the
operation it should perform will be added in subsequent patches.
Implements: blueprint data-copy-service
