dht: support auto-NUFA option
Many people have asked for behavior like the old NUFA, which builds and
seems to run but was previously impossible to enable/configure in a
standard way. This change allows NUFA to be enabled instead of DHT from
the command line, with automatic selection of the local subvolume on each
host.
