To Reproduce Steps to reproduce the behavior:

1. Deploy RHOSO18
2. Setup unified quota for glance
3. Setup the project specific limit with openstack limit command.
4. Run openstack limit list command to get the specified limit above.

Expected behavior

• openstack limit list executed by a user who has admin role with system scope should returns all limits for all projects.

Bug impact

• The operator needs to check keystone DB or they need to create admin role user per tenant and run the limit list command for each tenant

Known workaround

• An operator needs to create an admin role user per tenant to check the limit.
