make AbstractObject move constructible and move assignable

[untereiner]

Is your feature request related to a problem? Please describe.
I would like to transform the unordered_map from getDataObjects. However it is not possible to process it because the object behind of std::unique_ptr is not movable.

Describe the solution you'd like
Make AbstractObject movable or remove the unique_ptr

Describe alternatives you've considered
n.a.

Additional context

Hi Lionel,

The ownership of an AbstractObject is managed by the DataObjectRepository. So, I think I should even make AbstractObject non copyable (and still non movable).
Which kind of transform is not allowed? Could you share some few lines of codes?

Removing unique_ptr would somehow lead to the same result than getDataObjectsGroupedByDataType() (grouping by datatype instead of grouping by UUID), is it not OK with you?
You also have the option to loop on getUuids and then getDataObjectByUuid

getDataObjects returns unique_ptr because it is a direct (const) reference on the class member to get most of performance.
