Draft: feat: migration endpoint to move subproject from service group to data group
This merge requests creates a new endpoint to move users from service groups to datagroups
- If a data group does not exist on the subproject acls, a data group is created
- All users from service groups (if they exist) are moved from these groups to data admin and data viewer groups appropriately.
- Only subproject admins are allowed to perform this operation. If other users attempt to perform this operation, then the entitlements-svc will return user unauthorized errors
