[libvirt] [PATCH v6 3/7] qemu: Add Qemu capability for bps_max and friends
Add the capability to detect if the qemu binary have the capability
to use bps_max and friends
Add a value in the enum virQEMUCapsFlags for the qemu capability.
Set it with virQEMUCapsSet if the binary suport bps_max and they friends.
