Price Book: Save and Read prices

[magento-engcom-team]

Need to save prices in the internal storage inside Pricing service

Service methods implementation:

rpc assignPrices(AssignPricesRequest) returns (PriceBookAssignPricesResponse); 
rpc unassignPrices(UnassignPricesRequest) returns (PriceBookUnassignPricesResponse);
rpc getPrices(GetPricesRequest) returns (GetPricesOutput);

Repo: https://github.com/magento/storefront-pricing-ce Design: https://github.com/magento/architecture/blob/master/design-documents/storefront/pricing.md#price-books

AC:

• Prices successfully saved to PriceBook inside pricing service
• implement service methods: assignPrices, unassignPrices, getPrices
• Implement fallback price resolving (search price in parent price book if price not found in given one)  

Tech Details:

Here is the proposed structure for internal Storage (e.g. elastic indexers), but it may have any columns, that necessary 

| pricebook*id | id  | regular_price |   price | maximum_regular_price | maximum*price |  qty |

• For any given ID (product, custom options,..) price MUST be assigned to Default Price Book first (if price Default Price Book price is empty)
  • Default Price book holds prices regardless of scope.
• if Website AND Customer Group is NULL (or "0") price of Default Price Book Price must be updated
• If Website OR Customer Group is not NULL (or not 0) AND price for Default Price Book is NOT empty AND the price is different: save price for custom Price Book
• cover with integration tests (use fake data for AssignPricesRequest) the following cases for "getPrices" service:
  • get a price from Specific Price Book Id, when price is saved only in Default Price Book
  • get a price from Specific Price Book Id, when custom price is present for given Price Book
  • get a price from Specific Price Book Id, when custom price is present for "parent" Price Book (consider nested levels of price books: default/price-book1/price-book2/... , where "price-book1" will be taken if no price found in "price-book2"
  • Throw an Exception when Price is NOT present in Default Price Book
