[Libguestfs] [PATCH v2v 0/2] output: Remove -o json mode [in stages]

I'd like to remove the unused -o json mode. The implementation is over-complicated and the only potential user (KubeVirt) isn't using it now and would be better off with a proper -o kubevirt mode, which I'm going to implement later. My plan would be to add the patches in two stages. The first patch, which only removes the documentation but leaves the feature and test, would be applied to stable branch virt-v2v 2.0. The second patch would be go on the development branch 2.1 (which hasn't yet been created). The first stable release without this feature would be 2.2. For RHEL I'd probably put both patches in 9.1, even though we're planning to ship virt-v2v 2.0.x there. It means there will be an option/feature present in RHEL 9.0 which is removed in 9.1. Rich.
