Sam Betts a7f0af722f Support LLDP data as part of interfaces in inventory
To support multi-tenant networking in Ironic we need to be able to
discover not just the NICs a baremetal machine has but also the physical
connectivity to switches in the network.

This patch collects LLDP (Link Layer Discovery Protocol) data as part of
the list interfaces stage of the generic hardware manager. This
information can then be processed by the ironic inspector to populate
the local link information on each ironic port.

The processing done on this data in ironic python agent is limited, this
is to allow for server side processing hooks to process as much or as
little of the data as they want. This is to allow for multi-vendor
environments that might use different parts of the LLDP packet to use a
generic ramdisk and configure the processing server side using inspector
plugins.

Reserved fields switch_port_descr and switch_chassis_descr have been
deprecated for removal in Ocata in favor of passing the whole packet.

features:
- Add support for LLDP data in the returned inventory when option
collect_lldp is set to True. Each interface returned in the inventory that
receives an LLDP packet will contain the whole LLDP packet represented as a
list of TLVs in the field 'lldp'.
upgrade:
- Deprecated reserved fields switch_port_descr and switch_chassis_descr in
favor of returning the whole LLDP packet for each interface so that IPA
processing of this data remains generic and full processing can be
customised server side instead of having to create custom ramdisks. These
fields will be removed in Ocata.
