1. Add grouped product with individual quantity to cart using rest api #26909: Add grouped product with individual quantity to cart using rest api

Manual testing scenarios (*)

These steps assume Magento sample data is installed. Otherwise, update the body of the calls to match your database.

1. Generate a customer token by sending a post request to the rest/V1/integration/customer/token endpoint with a body of:
   { "username": "roni_cost@example.com", "password": "roni_cost3@example.com" }

2. Create an empty cart by sending a post request to the rest/V1/carts/mine endpoint. The bearer token should be the token returned by step 1 and the body should be empty.

3. Add a grouped product to cart by sending a post request to the rest/V1/carts/mine/items endpoint with a body of:
   The quote_id parameter in the body should be the quote ID returned by step 2. The bearer token should be the token returned by step 1.

{ "cartItem": { "sku": "gr", "qty": 1, "quote_id": "5", "product_option": { "extension_attributes": { "grouped_options": [ { "id": 2, "qty": 3}, { "id": 3, "qty": 2} ] } } } }

4. Get the cart contents by sending a get request to the rest/V1/carts/mine endpoint. The bearer token should be the token returned by step 1 and the body should be empty.

Is it normal that the "database compare" check run for 4.5hours and its still not finished?

[shawnabramson]

@bgorski The checks are still running like 10 hours later. Is this typical?

This PR is ready for review, not sure why its failing unit tests
