Updated the series according the last round of feedback and retested it. In
order to pass the 'make check' check this version depends on the upcoming revert
of 26664dff17b6 ("Do not suppress any shellcheck warnings") as discussed in the
v3 thread.

original cover letter:

Introduce helpers to setup nvmet targets. This is spin off from the refactoring
patches and the allowed_host patches [1].

Sagi suggested to record all resources allocated by nvmet_target_setup and then
later clean them up in nvmet_target_cleanup. I opted to figure out in
nvmet_target_cleanup what was allocated via the newly introdcuded _get_nvmet_ports
helper. The reason being, Hannes told me offline that he would like to add ANA
tests which will add some more ports to the subsystem. I hope with this
the code is more future proof.

BTW, while looking at this I saw that the passthru code is using the awkward
return value port when calling nvmet_passthru_target_setup. It seems some
more refactoring is in order...

changes

v4:
 - introduced _cleanup_blkdev helper
 - fixed --blkdev arguments passing
 - added unknown argument warning to _nvmet_target_setup argument parser
 - added rb tag

v3:
 - rebased/retested
 - use the default with _nvmet_target_setup
 - https://lore.kernel.org/linux-nvme/20230822083812.24612-1-dwagner@suse.de/

v2:
 - drop local subsys variable in passthru tests
 - do not use port as handle in passthru tests
 - free port after unregistering from subsys
 - https://lore.kernel.org/linux-nvme/20230818141537.22332-1-dwagner@suse.de/

v1:
 - https://lore.kernel.org/linux-nvme/20230818095744.24619-1-dwagner@suse.de/

    setup and cleanup

There is no need to introduce an extra local variable when it
uses the default subsysnqn anyway.

The passthru nvmet setup and cleanup helpers are using the port as
handle to track resources.

Instead returning the port from the setup call, we figure out in the
cleanup code which resources have been allocated. This avoids passing
around awkward handles.

Almost all fabric tests have the identically code for
setting up and cleaning up the target side. Introduce
two new helpers.

Thanks Daniel for this v4 series. All patches looks good, except one thing
in this patch.

As I noted for v3, I think the line above should be,

	_nvmet_target_setup --blkdev file

If the change is ok for you, I'll add this fix up and apply the series.

Sorry, I didn't see it in the response. Sure thing, no objection from my
side.

I've applied the series with the fix noted for the 3rd patch. I also reverted
the commit 26664dff17b6 together. Thanks again for this clean up :)
