[Libguestfs] [p2v PATCH 02/11] Introduce "p2v.output.misc" for passing "-oo" options to virt-v2v
From: Alban Lecorps <alban.lecorps(a)ubisoft.com>
The "-oo" option will be useful primarily for the openstack output mode
(currently disabled, from commit b74c126629e3, "Ignore 'openstack'
driver", 2020-03-16).
Use a ConfigStringList knob for "-oo", and for each OPTION=VALUE element
in that list, create a separate "-oo OPTION=VALUE" option. Do this because
there are too many "-oo" options, and because they are output-dependent,
and because even virt-v2v "blindly" forwards some of those (such as "-oo
os-*=*" for openstack).
The "p2v.oo" shorthand is not needed for compatibility, but it's still a
good idea for user convenience.
(Various tweaks, documentation, and test case update, by Laszlo.)
