The first installment in the effort of refactoring the device module.
The change can be made little by little as exandra and cqex queries can coexist.
This change ports a few queries to exandra, without making any big logic refactor, but we can see the future direction of this refactor: Astarte.AppEngine.API.Device.Queries becomes a module to expose queries and not data from the database directly.
For this iteration, this is enough to elegantly use the queries in the Device module, but more complex queries may require a more in-depth refactor.
The following queries have been ported:
retrieve_interfaces_list
retrieve_all_endpoints_for_interface!
retrieve_mapping
prepare_value_type_query
/execute_value_type_query
