docs: Deploys a json network to a specific cluster.<p>
  
  The JSON network configuration will be converted to a {@link NetworkConfig} before
  being deployed to the cluster. The conversion is done synchronously, so if the
  configuration is invalid then this method may throw an exception.
  
  @param cluster The cluster to which to deploy the network.
  @param network The JSON network configuration. For the configuration format see
  the project documentation.
  @return The Vertigo instance.
