Different networks in environment templates

This blueprint involves the possibility of having different networks in the different applications which compose an environment template. For instance, having the typical architecture load balancer-web server-database in the definition of an environment template, the idea is to have two different networks: i) database network among the web server and database applications and ii) server network between the load balancer and the server. This feature besides including this information in the environment template object, it requires the possibility of creation different networks in the same environment.
