[PATCH i-g-t v3 0/5] RFC: Add attachments support

["Zbigniew Kempczyński" <zbigniew.kempczynski@intel.com>]

This series introduces support for hook/test written attachments.
It is somehow limited and stiff but allows to write anything test/hook
wants in attachments directory. File names which occured in attachments
directory are added to results.json.

Series targets our need to include guc logs for failed tests especially
in the point of time when it occurs.

v2: - added clearing of attachments dir in overwrite mode
    - guc-log hook script is now installed to igt datadir/hooks dir
    - added hook-exec-allowlist to selectively execute hook scripts
v3: - drop hook-exec-allowlist in runner, now scripts are filtering
      allowlist on their own
    - add support for attachments in recursive directories
