New Module to enable MSI for Configurable Product GraphQl

Description

Added a new module to enable MSI for Configurable Product GraphQl.
The Magento_InventoryConfigurableProduct module is overriding the Magento_ConfigurableProduct_Plugin_Model_ResourceModel_Attribute_InStockOptionSelectBuilder plugin, but no module is overriding the Magento_ConfigurableProduct_Plugin_Model_ResourceModel_Attribute_InStockOptionSelectBuilder_GraphQl plugin.
This new module solves the issue.

Fixed Issues

Using graphql to read a configurable product options leads to have an empty array of option values.
This happens because the Magento_ConfigurableProduct_Plugin_Model_ResourceModel_Attribute_InStockOptionSelectBuilder_GraphQl plugin uses a SQL query joining the module-catalog-inventory tables instead the module-inventory tables.

Manual testing scenarios

1. Create a new inventory source
2. Create a new inventory stock associated with websites and the new inventory source
3. Create Configurable Product and variants
4. Create new “in stock” Source Items on the new Inventory Source for the product variants
   
5. Remove Default Source Items
6. Run graphql

query getProductDetailForProductPage($urlKey: String!) {
  products(filter: { url_key: { eq: $urlKey } }) {
    items {
      id
      ... on ConfigurableProduct {
        configurable_options {
          attribute_code
          attribute_id
          id
          label
          values {
            default_label
            label
            store_label
            use_default_value
            value_index
            swatch_data {
              ... on ImageSwatchData {
                thumbnail
              }
              value
            }
          }
        }
      }
    }
  }
}

7. products.items.configurable_options.values should return an array of values

Hello @bordeo,

Thank you for your collaboration!

We have tried to reproduce the issue in the latest development branch, but it seems the issue is not reproducible for us. We have followed the below steps to reproduce the issue:

1. Create a new inventory source
2. Create a new inventory stock associated with websites and the new inventory source
3. Create Configurable Product and variants
4. Create new “in stock” Source Items on the new Inventory Source for the product variants:

5. Remove Default Source Items 6. Run graphql ```gql query getProductDetailForProductPage($urlKey: String!) { products(filter: { url_key: { eq: $urlKey } }) { items { id ... on ConfigurableProduct { configurable_options { attribute_code attribute_id id label values { default_label label store_label use_default_value value_index swatch_data { ... on ImageSwatchData { thumbnail } value } } } } } } } ``` We can see the `products.items.configurable_options.values` in the output as below:

{
  "data": {
    "products": {
      "items": [
        {
          "uid": "MTIyOQ==",
          "configurable_options": [
            {
              "attribute_code": "attributeset2attribute1",
              "attribute_uid": "MTg1",
              "uid": "Y29uZmlndXJhYmxlLzEyMjkvMTg1",
              "label": "Attribute Set 2 - Attribute 1",
              "values": [
                {
                  "default_label": "Attribute Set 2 - Attribute 1 - Option a",
                  "label": "Attribute Set 2 - Attribute 1 - Option a",
                  "store_label": "Attribute Set 2 - Attribute 1 - Option a",
                  "use_default_value": true,
                  "value_index": 22,
                  "swatch_data": null
                },
                {
                  "default_label": "Attribute Set 2 - Attribute 1 - Option b",
                  "label": "Attribute Set 2 - Attribute 1 - Option b",
                  "store_label": "Attribute Set 2 - Attribute 1 - Option b",
                  "use_default_value": true,
                  "value_index": 23,
                  "swatch_data": null
                },
                {
                  "default_label": "Attribute Set 2 - Attribute 1 - Option c",
                  "label": "Attribute Set 2 - Attribute 1 - Option c",
                  "store_label": "Attribute Set 2 - Attribute 1 - Option c",
                  "use_default_value": true,
                  "value_index": 24,
                  "swatch_data": null
                }
              ]
            }
          ]
        }
      ]
    }
  }
}

It seems the issue has been resolved, hence we are closing this PR.
