CoffeeMachineRestApiV3:0.10.0

New version V3 is separated from V2 because it has additional dependencies and additional models. Models from V3 are still backward compatible with V2 version.

V3 stores both in-memory and in database. Ingredients and Denomination are stored in-memory first so we can compute drinks calculation faster. After all calculations are done, there is a transaction to database to store all values and in same transaction in-memory is also stored. If any calculations fail, nothing will be saved.
