[libvirt PATCH v2 3/5] qemu_monitor: add support for get qemu migration blockers

[Eugenio Pérez <eperezma@xxxxxxxxxx>]

since qemu 6.0, if migration is blocked for some reason, 'query-migrate'
will return an array of error strings describing the migration blockers.
This can be used to check whether there are any devices blocking
migration, etc.

Enable qemu monitor to send this query.
