* refactor: remove duplicated data collection in old wifi module
Still a bit more work before we can fully remove it
* remove unused graphs
update overview graphs for some wireless os
* feature: Allow snmpget in os discovery yaml
Re-submit after release
* Remove extra trim in discovery and in snmp_get.
also trim() always returns a string, so is_string() check is a waste of cpu cycles.
* feature: Allow snmpget in os discovery yaml
Convert all remaining os except airos.
Affected OS: asuswrt-merlin, ddnons, dsm, extrahop, huaweiups, ibmtl, pcoweb, pktj, qnap, remoteeye4, sentry3, sentry4, tomato

* Fix, asuswrt-merlin and tomato with snmpsim. May not have been an issue with actual devices because of -Oa leading " was a bit odd.
* missed file
