Daniel P. Berrange 6bc37dccec 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

commit da217205f5

    virt: Use preexec_fn to ulimit qemu-img info call

NOTE (kchamart) [stable/liberty]: Add a check for the presence of
'ProcessLimits' attribute (which is only present in
oslo.concurrency>=2.6.1; and a conditional check for 'prlimit' parameter
in qemu_img_info() method.

Upstream discussion[1][2] that led to merging this patch to
stable/liberty branch.
