Dummy Data: point shop

[lasyaneti]

1. for now, create new database called shop, create a collection within that called items
2. each item should store name (string), quantity (int), price (int), isRaffle (boolean)
3. add an endpoint GET /shop that returns this entire collection and mobile can dynamically update the status of the point shop

Add in an itemId field that's uniquely generated per item. Should create two tables, one for actual data and 1 for available quantities (because then we can modify that better). Add functionality to post/put/delete item, and put quantity.
