Handle loading spinner on API calls

[omar-chahbouni-decathlon]

What it's the actual situation on ARA ? The loading spinner is manually managed by using a (boolean) variable to show/hide it depending on its current state (e.g. waiting for the API call to finish, errors, etc.). Although this works, there are a few disadvantages:

• This is extra work
• It can be error prone (e.g. forgetting to end the spinner)
• You can forget to add it
• It is not a good practice

Describe the solution you'd like An interceptor is a good solution.

IMPORTANT: Don't forget to delete all the "manual" spinners
