[PATCH blktests v4 0/5] Add support to run against arbitrary targets

[Aurelien Aptel <aaptel@nvidia.com>]

This series is based off Daniel's patches. It is rebased to work on
current blktests. It is also available on github:

    https://github.com/aaptel/blktests.git branch remote-target-v4

The last patch adds a test making explicit use of the remote target
support by testing the new nvme-tcp offloading.

I've added a 'blkdev' setting under [subsys_0] in the control script
config to specify the backing block device on the target, instead of
hardcoding '/dev/vdc'.

changes:
v4:
  - added nvme test 055 for nvme-tcp offload
  - added 'blkdev' setting under [subsys_0] in the control script config
  - added workaround for older python versions
v3:
  - added support for previous configured target
  - renamed nvme_nvme_target to	_require_kernel_nvme_target
  - use shorter redirect operator
  - https://lore.kernel.org/all/20240627091016.12752-1-dwagner@suse.de/
v2:
  - many of the preperation patches have been merged, drop them
  - added a python script which implements the blktests API
  - add some documentation how to use it
  - changed the casing of the environment variables to upper case
  - https://lore.kernel.org/all/20240612110444.4507-1-dwagner@suse.de/
