* Fix legacy os extend support Now compatible with oids that could have been used by older software: extend .1.3.6.1.4.1.2021.7890.2 hardware extend .1.3.6.1.4.1.2021.7890.3 manufacturer extend .1.3.6.1.4.1.2021.7890.3 vendor extend .1.3.6.1.4.1.2021.7890.4 serial And correct the oids for VERY old exec options. * Convert to SnmpQuery and convert some numeric oid to textual * MIB-Dell-10892::chassisServiceTagName.1 is discovered already in ServerHardware trait, no need to double fetch * OIDs were previously mixed up, fix data
