Bug description:
  Reported via private E-mail from Richard W.M. Jones.

  Turns out qemu image parser is not hardened against malicious input
  and can be abused to allocated an arbitrary amount of memory and/or
  dump a lot of information when used with "--output=json".

  The solution seems to be: limit qemu-img ressource using ulimit.

  Example of abuse:

  -- afl1.img --

  $ /usr/bin/time qemu-img info afl1.img
  image: afl1.img
  [...]
  0.13user 0.19system 0:00.36elapsed 92%CPU (0avgtext+0avgdata 
642416maxresident)k
  0inputs+0outputs (0major+156927minor)pagefaults 0swaps

  The original image is 516 bytes, but it causes qemu-img to allocate
  640 MB.

  -- afl2.img --

  $ qemu-img info --output=json afl2.img | wc -l
  589843

  This is a 200K image which causes qemu-img info to output half a
  million lines of JSON (14 MB of JSON).

  Glance runs the --output=json variant of the command.

  -- afl3.img --

  $ /usr/bin/time qemu-img info afl3.img
  image: afl3.img
  [...]
  0.09user 0.35system 0:00.47elapsed 94%CPU (0avgtext+0avgdata 
1262388maxresident)k
  0inputs+0outputs (0major+311994minor)pagefaults 0swaps

  qemu-img allocates 1.3 GB (actually, a bit more if you play with
  ulimit -v).  It appears that you could change it to allocate
  arbitrarily large amounts of RAM.

Author: Hemanth Makkapati 
Date:   Fri Sep 23 09:29:12 2016 -0500

Adding constraints around qemu-img calls

* All "qemu-img info" calls are now run under resource limitations
  that limit CPU time to 2 seconds and address space usage to 1 GB.
  This helps avoid any DoS attacks via malicious images.
* All "qemu-img convert" calls now specify the import format so that
  it does not have to be inferred by qemu-img.

Limit memory & CPU when running qemu-img info

It was found that a modified or corrupted image file can cause a DoS
on the host when getting image info with qemu-img.

This uses the newer 'prlimit' parameter for oslo.concurrency execute
to set an address space limit of 1GB and CPU time limit of 2 seconds
when running the qemu-img info command.

Thank you for that info Jeremy, I've targetted it to the appropriate

Bug description:
  Reported via private E-mail from Richard W.M. Jones.

  Turns out qemu image parser is not hardened against malicious input
  and can be abused to allocated an arbitrary amount of memory and/or
  dump a lot of information when used with "--output=json".

  The solution seems to be: limit qemu-img ressource using ulimit.

  Example of abuse:

  -- afl1.img --

  $ /usr/bin/time qemu-img info afl1.img
  image: afl1.img
  [...]
  0.13user 0.19system 0:00.36elapsed 92%CPU (0avgtext+0avgdata 
642416maxresident)k
  0inputs+0outputs (0major+156927minor)pagefaults 0swaps

  The original image is 516 bytes, but it causes qemu-img to allocate
  640 MB.

  -- afl2.img --

  $ qemu-img info --output=json afl2.img | wc -l
  589843

  This is a 200K image which causes qemu-img info to output half a
  million lines of JSON (14 MB of JSON).

  Glance runs the --output=json variant of the command.

  -- afl3.img --

  $ /usr/bin/time qemu-img info afl3.img
  image: afl3.img
  [...]
  0.09user 0.35system 0:00.47elapsed 94%CPU (0avgtext+0avgdata 
1262388maxresident)k
  0inputs+0outputs (0major+311994minor)pagefaults 0swaps

  qemu-img allocates 1.3 GB (actually, a bit more if you play with
  ulimit -v).  It appears that you could change it to allocate
  arbitrarily large amounts of RAM.

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
