Mathieu Mitchell 61f2f07569 Introduce support for APC MasterSwitchPlus and Rack PDU
Provide 3 new snmp_driver values for different APC product families:
  - apc_masterswitch
  - apc_masterswitchplus
  - apc_rackpdu

The "apc" snmp_driver is still supported and maps to the MasterSwitch driver
to avoid breaking backwards compatibility.

Different APC product families support different OIDs for power control.
  - APC MasterSwitch uses sPDUOutletCtl
  - APC MasterSwitchPlus uses sPDUOutletControlMSPOutletCommand
  - APC Rack PDU uses rPDUOutletControlOutletCommand

===========
SNMP driver
===========
The SNMP power driver enables control of power distribution units of the type
frequently found in data centre racks. PDUs frequently have a management
ethernet interface and SNMP support enabling control of the power outlets.
The SNMP power driver works with the PXE driver for network deployment and
network-configured boot.
List of supported devices
=========================
This is a non-exhaustive list of supported devices. Any device not listed in
this table could possibly work using a similar driver.
Please report any device status.

============== ========== ========== =====================
Software Requirements
=====================
- The PySNMP package must be installed, variously referred to as ``pysnmp``
or ``python-pysnmp``
Enabling the SNMP Power Driver
==============================
- Add ``pxe_snmp`` to the list of ``enabled_drivers`` in
``/etc/ironic/ironic.conf``
- Ironic Conductor must be restarted for the new driver to be loaded.
Ironic Node Configuration
=========================
Nodes are configured for SNMP control by setting the Ironic node object's
``driver`` property to be ``pxe_snmp``. Further configuration values are
added to ``driver_info``:
- ``snmp_driver``: PDU manufacturer driver
- ``snmp_address``: the IPv4 address of the PDU controlling this node.
- ``snmp_port``: (optional) A non-standard UDP port to use for SNMP operations.
If not specified, the default port (161) is used.
- ``snmp_outlet``: The power outlet on the PDU (1-based indexing).
- ``snmp_protocol``: (optional) SNMP protocol version
(permitted values ``1``, ``2c`` or ``3``). If not specified, SNMPv1
is chosen.
- ``snmp_community``: (Required for SNMPv1 and SNMPv2c) SNMP community
parameter for reads and writes to the PDU.
- ``snmp_security``: (Required for SNMPv3) SNMP security string.
PDU Configuration
=================
This version of the SNMP power driver does not support handling
PDU authentication credentials. When using SNMPv3, the PDU must be
configured for ``NoAuthentication`` and ``NoEncryption``. The
security name is used analogously to the SNMP community in early
SNMP versions.
