As a developer, I want the network to be a data class

[frederique-hub]

The current NetworkIniConfigData should become a dataclass:

• This implies removing the NetworkIniConfigDataReader or convert it in a data builder.
• Network class might be renamed to NetworkController (or else), whose config argument becomes the NetworkIniConfigData.
• The current create should be broke down into different steps and generalized so we have "workflows".
  • Create specific workflows for each type of 'network' origin that there is. Delegating creation responsibility in said classes.
