From: Daniel P. Berrangé <berra...@redhat.com>
The various ACL related commands are obsolete now that the QAuthZ
framework for authorization is fully integrated throughout QEMU network
services. These only ever worked with VNC and were never used by libvirt.
Mark it as deprecated with no direct replacement to be provided.
Authorization is now provided by using 'object_add' together with
the 'tls-authz' or 'sasl-authz' parameters to the VNC server, and
equivalent for other network services.
