[PULL 4/9] iotests: Add more qemu_img helpers |
Date: |

From: Nir Soffer <nirsof@gmail.com>
Add 2 helpers for measuring and checking images:
- qemu_img_measure()
- qemu_img_check()
Both use --output-json and parse the returned json to make easy to use
in other tests. I'm going to use them in a new test, and I hope they
will be useful in may other tests.
