    virt: set address space & CPU time limits when running qemu-img
    This uses the new 'prlimit' parameter for oslo.concurrency execute
    method, to set an address space limit of 1GB and CPU time limit
    of 2 seconds, when running qemu-img.
    This is a re-implementation of the previously reverted commit

    in qemu_img_info() method.
