[API] View current Stock on Hand by Facility/Program

As a storeroom manager at a location that keeps stock, I want to know how much of each product I have on hand so that I know when I need to reorder, and so that other users higher in the health system know when I'm out of stock

Scope out:
Permission management, which facility can be chosen by the end user to view the corresponding SOH;
UI;
Month of stock covered by OLMIS-924;
Search function on the UI page;
Sort function on the UI page;
Max Stock Quantity is defined in OLMIS-887;
Min Stock Quantity defined in OLMIS-978;
Navigation on the UI page (e.g. Clicking on a product displays its electronic stock card (https://openlmis.atlassian.net/browse/OLMIS-625#icft=OLMIS-625);
Lot function related stuff;

Acceptance Criteria

1. The default chosen facility is the user's home facility.

2. The API request should include facility ID, program ID and a valid access token.

3. After receiving a valid API request, the API would response back the information of all products on the approved product List and their current SOH if they have

User can select the program they want to view products' SOH for. For selected program, system displays all the products available in the program in a list, along with the current SoH for each product.If no program is selected, display all products for the selected facility

Questions/notes from story's history to consider This is the first MVP story for stock management. The UI can be throw-away, or can be used as the basis for future additions (dev decision) Group by program potentially

Looking forward

• If lot management is "on", display SOH for the product by lots. Display expiry (Need to discuss UX for this)
  i.e.
  Paracetemol 120
  Lot A 75
  Lot B 45

• Display/sort based on expiry (make this configurable)

• Do we want the concept of "favorites" where users can save favorites and re-add products?

• months of stock-
