block: add snapshot info query function bdrv_query_snapshot_info_list()
This patch adds function bdrv_query_snapshot_info_list(), which will retrieve snapshot info of an image in qmp object format. The implementation is based on the code moved from qemu-img.c with modification to fit more for qmp based block layer API.
