Declares DOCKERDISC_IMPORT_ON (default on) so an operator can fully opt
this plugin out of CurrentScan promotion. Needed because
DOCKERDISC_CREATE_DEV alone doesn't cover it: a macvlan/ipvlan
container's row always carries a real scanMac, so even with
CREATE_DEV off, an already-existing device for that MAC (found
independently by ARP/Nmap) still gets its presence/devLastIP/
devParentMAC updated by this plugin on every run - only IMPORT_ON can
turn that off. The two settings are independent, per jokob-sk's PR
feedback - IMPORT_ON gates promotion for the whole run, CREATE_DEV
gates device creation per row.
Also adds missing docstrings to process_host()/main() (CodeRabbit
docstring-coverage check), matching the style already used elsewhere
in this file.
