cli: Add 'rad node inventory --nid <nid>' — heartwood

This gives the possibility to see the inventory of another node than self. This does replicatee the functionality of ‘rad node routing –nid’, but feels like a more intuitive command to try.

     rad node debug [<option>...]
     rad node connect <nid>@<addr> [<option>...]
     rad node routing [--rid <rid>] [--nid <nid>] [--json] [<option>...]
     rad node inventory [<option>...]
     rad node inventory [--nid <nid>] [<option>...]
     rad node events [--timeout <secs>] [-n <count>] [<option>...]
     rad node config [--addresses]
     rad node db <command> [<option>..]

     --nid <nid>          Show the routing table entries for the given NID
     --json               Output the routing table as json
 Inventory options
     --nid <nid>          List the inventory of the given NID (default: self)
 Events options
     --timeout <secs>     How long to wait to receive an event before giving up
