This function will simply call qmp interface qmp_query_snapshots()
added in last commit and then dump information in monitor console.
Now snapshot info retrieving code in qemu and qemu-img are merged
by calling same block layer function, and then they just translate
the qmp object to strings in stdout or monitor console.
Note:
This patch need previous hmp extention patch which enable
info sub command take qdict * as paramter.
