  Version 5.2.0 hangs and eventually fails when running openstack image

Bug description:
  Hi,

  I'm facing exactly following issue already reported on OpenStack:
  https://storyboard.openstack.org/#!/story/2007672

  
  ubuntu at server:~/it/infra$ openstack image save --file server-snap-1.qcow 55b81c1c-b7cd-45d8-9fba-df23b854c697
  Killed

  OS version:
  ubuntu at server:~$ lsb_release -a
  No LSB modules are available.
  Distributor ID:	Ubuntu
  Description:	Ubuntu 20.04.1 LTS
  Release:	20.04
  Codename:	focal

  openstackclient version:
  ubuntu at server:~$ apt list --installed | grep openstack
  python3-openstackclient/focal,now 5.2.0-0ubuntu1 all [installed]
  python3-openstacksdk/focal,now 0.46.0-0ubuntu1 all [installed,automatic]
  ubuntu at server:~

  dmesg output:

  [353903.071020] oom-kill:constraint=CONSTRAINT_NONE,nodemask=(null),cpuset=/,mems_allowed=0,global_oom,task_memcg=/user.slice/user-1000.slice/session-120.scope,task=openstack,pid=34479,uid=1000

  [353903.229612] oom_reaper: reaped process 34479 (openstack), now anon-rss:0kB, file-rss:0kB, shmem-rss:0kB

  I'd expect to be able to save image to a file and not in memory.

  Thanks
