Every option in this file is about QEMU so don't need that
as a name prefix. 'gfapi' is also pretty obscure naming.
Lets just call it 'glusterfs_debug_level'

I think you might need a capability check aganist QEMU to see if 'debug'
is a permitted parameter before using it, unless some existing capability
check is sufficient }
