Add a new pdutype (genpdu) for PDUs implementing the Raritan PDU2-MIB. A single MIB covers the Raritan PX2/PX3/PX4/PXC/SRC/PXO/BCM series, the Server Technology PRO3X/PRO4X series, the Legrand intelligent PDUs, and all PDUs following the PDU2-MIB. Supports rpower (whole-PDU and per-outlet), rinv and rvitals over SNMP v1, v2c or v3, with credentials read from the pdu table). Unlike the existing types, sensor units and decimal precision are read from the MIB per sensor rather than hardcoded, so readings are correct across models that report differing precision for the same sensor. Outlet switching capability is probed at connect time, so metered-only models report a single "unsupported" message instead of a per-outlet error. rspconfig is not supported for genpdu; PDU linking and BCM2/PMC power meters are out of scope. Tested on Raritan PX4-5851-E7V2 (fw 4.2.10.5-50400, switched), PX3-1901U-N1 and PX3-1901U-N1A6 (fw 4.0.20.5-49038, metered), and PX2-1901U-N1A6 (fw 4.0.20.5-49038, metered).

Power Distribution Units (PDUs) are devices that distribute power to servers in a frame. They have the capability of monitoring the amount of power that is being used by devices plugged into it and cycle power to individual receptacles. xCAT can support three kinds of PDUs, infrastructure PDU (irpdu), collaborative PDU (crpdu) and generic SNMP PDU (genpdu).

The Infrastructure rack PDUs are switched and monitored 1U PDU products which can connect up to nine C19 devices or up to 12 C13 devices and an additional three C13 peripheral devices to a single dedicated power source. The Collaborative PDU is on the compute rack and has the 6x IEC 320-C13 receptacles that feed the rack switches. The generic SNMP PDU is any PDU driven by the Raritan PDU2-MIB, which covers the Raritan PX2/PX3/PX4/PXC/SRC/PXO/BCM series, the Server Technology PRO3X/PRO4X series and the Legrand intelligent PDUs. These types of PDU have different design and implementation. xCAT has different code path to maintains PDU commands via **pdutype**.
