docs: Deploys a network to a specific cluster.<p>
  
  If the given network configuration's name matches the name of a network
  that is already running in the cluster then the given configuration will
  be <b>merged</b> with the running network's configuration. This allows networks
  to be dynamically updated with partial configurations. If the configuration
  matches the already running configuration then no changes will occur, so it's
  not necessary to check whether a network is already running if the configuration
  has not been altered.
  
  @param cluster The cluster to which to deploy the network.
  @param network The configuration of the network to deploy.
  @return The Vertigo instance.
