Change Duo Pro bulk assign lib to a service
What does this MR do and why?
- Change the Duo Pro bulk assign lib to a service
- We previously implemented bulk assign as a library. In this particular issue https://gitlab.com/gitlab-org/gitlab/-/issues/442284, we required a service for bulk assignment within the UI.
- In this MR, we're not introducing any new functionality; rather, we're simply transitioning the library to function as a service and building on top of it on later MRs.
How to set up and validate locally
- Green specs are enough
