Users can only update the following properties of a billing group

• Description
• Tags

Backend:

• Create/update a service that:
  • Sends a request to AWS to update a billing group: You can use the method UpdateBillingGroupAsync to do that
  • If the request is successful, the billing group should be updated on database using EF
  • Otherwise an exception should thrown with a human readable message
• Create a REST endpoint that allow HTTP clients to update a billing group
  • ⚠️ Use DTO for data exchange between controllers and services layers. Controllers should never handle AWS or internal objects.

Frontend:

• Create a new view to allow users to update a billing group
• Validation on data must gate the send button
• Users must be able alerted when an exception occurs
• The view should also allow to delete the billing group
