tools: nfdc status commands

These commands are added to nfdc:

    status show
    face list
    channel list
    strategy list
    fib list
    route list

They are implemented by calling into legacy nfd-status procedures,
and currently do not support filtering arguments.
Future commits will re-implement them directly with StatusReport.
