From: Peter Krempa <pkrempa@redhat.com>

Add an example of 250 layer deep nested JSON to make sure the parser
supports it. This is in order to maintain compatibility with external
snapshots in qemu, where such a deeply nested document is returned with
a 'query-block' QMP call.

I've used a fake JSON as a real reply from qemu is around 1.4MiB for a
200 deep image chain.

As promised for the JSON nesting fix. Obviously works only when applied
on top of it.
