Code Issues Proposed changes

Use the json format output of qemu-img info

Browse Source 
Support for the human format by oslo_utils.imageutils.QemuImgInfo was
deprecated since oslo.utils 4.9.1 [1]. This change replaces the human
format with the json format which will be used by default.

[1] 73eb0673f627aad382e08a816191b637af436465

Backport note: The json format is preferable because it allows access
to format specific details (since oslo.utils 4.1.0).  These details
are not present when the default 'human' format is used.  See change
I133da07a5a9628b8a9 for details.
