[PATCH blktests v4 0/3] Introduce nvmet target setup/cleanup helpers

[Daniel Wagner <dwagner@suse.de>]

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...
