[one-users] Add network context variables automatically

[Javier Fontan]

That feature will come in 4.0. You will be able to use '--net_context'
to fill the network configuration in the contextualization [1]. In
Sunstone will also be an option that will fill the variables for you.

Meanwhile you will need to add the network paramaters to the context
part manually [2].
