Only Gerrit administrators should be able to change the parent of a project because by changing the parent project access rights and BLOCK rules which are configured on a parent project can be avoided. The set-project-parent SSH command already verifies that the caller is a Gerrit administrator, however project owners can change the parent project by modifying the project.config file and pushing to the refs/meta/config branch. This change ensures that changes to the project.config file that change the parent project can only be pushed/submitted by Gerrit administrators. In addition it is now not possible anymore to - set a non-existing project as parent (as this would make the project be orphaned) - set a parent project for the All-Projects root project (the root project by definition has no parent) by pushing changes of the project.config file to refs/meta/config.
