Subject: qemu-config: load modules when instantiating option groups
Git-commit: 632a8873500d27022c584256afc11e57e2418b94
Right now the SPICE module is special cased to be loaded when processing
of the -spice command line option. However, the spice option group
can also be brought in via -readconfig, in which case the module is
not loaded.
Add a generic hook to load modules that provide a QemuOpts group,
and use it for the "spice" and "iscsi" groups.
Fixes: #194
