- The method get_objstorage at the module top_level allows to easily create an ObjStorage given a unique class key and a dictionary of matching arguments.
- Add the get_batch method to the base API so it is now possible to perform a get of multiple contents at the same time. This should be an improvement for the remote objstorage.
- Align the RemoteObjStorage api to the bas ObjStorage one, and also update the tests that now uses the base tests for ObjStorage's implementations, which makes the code much simpler.
