Subject: [PATCH] support import previous compatible load

Add support for importing load with import.sh from the current load.
This enables to always import load with higher version import.sh (in the
case of load-import --inactive)

TCs:
    passed: from system controller running 23.09 load, import 22.12 load
    passed: regression import N+1 load

Story: 2010611
Task: 48371
