Description

The current code requests list of all faces and then filters multicast faces.

Face query offloads filtering operation to NFD and simplifies code of ndn-autoconfig.

Why udp*4* only? Even if multicast udp6 is not supported by NFD at the moment, it might be in the future.

Why udp*4* only? Even if multicast udp6 is not supported by NFD at the moment, it might be in the future.

Face query operation can only support one set of conditions.
Querying "(udp4 or udp6) and multicast" requires two query operations "udp4 and multicast" and "udp6 and multicast".

HubDiscovery protocol just says "a multicast face", so the correct condition is just "multicast".

https://gerrit.named-data.net/3349 moves ndn-autoconfig to nfd::tools::autoconfig namespace, to be consistent with nfdc.
https://gerrit.named-data.net/3350 changes MulticastDiscovery to use FaceQueryDataset.

IntegrationTests are failing due to a limitation of Emulab integ runner. The previous code filters faces by "UDP with IPv4 multicast address" condition; https://gerrit.named-data.net/3350 uses link-type=multi-access face query filter, which includes both UDP and Ethernet multicast faces. The Emulab integ runner has blocked UDP multicast with iptables, but does not block Ethernet multicast.

#1712 came just in time to offer a blacklist for Ethernet multicast faces. I manually executed sudo infoedit -f /usr/local/etc/ndn/nfd.conf -s face_system.ether.blacklist.subnet -v 155.98.0.0/16 on each host, and then the HUB discovery test scenario is passing.
I'll work on a solution on Emulab integ runner side. In the meanwhile, this one is ready to go.
