The Add method on the multinode DB interface accepts
a set of parameters which are already fields in the nodes.Node struct
excluding the name field.
When adding a new node, you're forced to call UpdateName() method
after calling the Add() method in order to save a node and update
the name.
This change allows passing the nodes.Node entity which includes
the name field. With this, a new node can be added together with
the name without invoking the UpdateName() method.

This change adds an add command to the multinode CLI.
The add command takes a json <file> as argument.
If dash (-) is specified, it reads data from stdin.
The <file> specified can be json file containing array of
nodes data or a single node object.
