Add an extended view for objects to show all of their relations

[jathanism]

If for example you run nsot networks list -c 10.10.10.1/32 you just get the output for that network itself:

$ nsot networks list -c 10.10.10.1/32
+-------------------------------------------------------------------------------+
| ID   CIDR (Key)      Is IP?   IP Ver.   Parent          State      Attributes |
+-------------------------------------------------------------------------------+
| 5    10.10.10.1/32   True     4         10.10.10.0/24   assigned              |
+-------------------------------------------------------------------------------+```

This idea is what if we add some kind of flag for "extended" view, it would also include other relations, something like:

$ ./nsot networks list -c 10.10.10.1/32 --extended
Network
+-------------------------------------------------------------------------------+
| ID   CIDR (Key)      Is IP?   IP Ver.   Parent          State      Attributes |
+-------------------------------------------------------------------------------+
| 5    10.10.10.1/32   True     4         10.10.10.0/24   assigned              |
+-------------------------------------------------------------------------------+

Assignments
+---------------------------+
| ID   Hostname   Interface |
+---------------------------+
| 2    lax-rtr1   eth0      |
+---------------------------+

Parent
+-------------------------------------------------------------------------+
| ID   CIDR (Key)      Is IP?   IP Ver.   Parent   State       Attributes |
+-------------------------------------------------------------------------+
| 4    10.10.10.0/24   False    4         None     allocated              |
+-------------------------------------------------------------------------+

Eh? Something like this? Perhaps in a more easily consumable format that isn't just a bunch of tables being output?
