Prevent to run concurrently some module tests
Some modules like `account_payment_stripe` and `web_shop_shopify` have issue to run concurrently.
(I suspect that the web services slow down the processing)
Se we could use the [resource group](https://docs.gitlab.com/ee/ci/resource_groups/) to prevent to run them concurrently.
I think `.gitlab-scripts/generate-ci.py` could be extended to add a `resource_groups` with the name of the module for a list of module.
