This allows to have a better "Prevent automatic project creation" feature (previously managed through a single property, see SONAR-68861).
The impacts are:
- on a fresh instance, I expect "Anyone" to have the "provisioning" permission in order to have a good first UX with SQ when analysing a project for the very first time
- a DB migration is required to grant the "provisioning" permission to every user/group that already has the "scan" permission
On a side note, this was also needed to be able to correctly implement the queue of pending report (which need an existing UUID for projects/views).
