This adds a service to remove a user from an On-call Rotation.

We ensure that the rotation is up to date by running the job top persist current shifts. Then, we update the `is_removed` boolean on the Participant model associated to the user/rotation.

Deletion from rotations are scoped to the member being removed:

- If a member is a project member, only that project's rotations are affected
- If a member is a group member, all of the projects within that group are affected

**Why don't we use the existing [`EditRotationService`](https://gitlab.com/gitlab-org/gitlab/-/blob/9c35c043a9ce9d70bd30ec6dc0d30991bf15ab29/ee/app/services/incident_management/oncall_rotations/edit_service.rb) service?**
The `EditRotationService` requires you to provide all `participant` params for all remaining participants, and in a format which requires the `user`, `color_palette`, `color_weight` etc. Rather than modify the `EditRotationService` to  make this easier, I chose to make a specific service for this use case.
