Extend NetworkInterface status with LLDP neighbor information

[xkonni]

Proposed Changes

This PR allows the metal-api to hold more information about the server. It is based on #452 and the first commit is actually from that PR, as it was not yet merged.

• update crd
  • add all networkInterfaces, include ipv4 + ipv6 ips and status
  • add lldp information
• update registry
  • lldp was added in Add hardware detail extraction to metalprobe (inventory) #452
  • update networkInterface with ipv6 addresses and carrierStatus
• update controller to feed the newly available data in the registry into the crd

From our discussion:

This PR should take information from the registry, provided by #452 and update the networkInterfaces struct in the servers crd.

Example:

... 
networkInterfaces:
  - name: enp123  
    carrierState: up/down
    macAddress: aa:bb:cc:dd:ee:ff
    ipAddresses: [] # v4 and v6
    neighbors:
      - macAddress: 44:ae:25:78:db:41
        portDescription: topology/pod-1/protpaths-2115-2116/pathep-[openstack-baremetal-node008-bb097]
        portID: Eth1/17
        systemDescription: topology/pod-1/node-2116
        systemName: qa-de-1-aci-2116-bb097
  - name: enp456

#452 is still part of this PR, I though the plan was to merge it separately?

@xkonni can you please rebase this PR?

rebased, updated with our discussed changes and more robust lldpctl output parsing.
