Disallow the registration of runners to all groups and projects to just admins (Self-Managed)
Description
There may be times where server admins provide shared runners and, due to security concerns, they want to limit/prevent/gate users from registering runners to a project.
Proposal
- disallow the registration of runners to all groups and projects
- still allow in the Admin area to change a shared runner to specific on a group/project.
