- [node] : The node to configure

summary:
 Remotely configures and starts ONOS for the first time.

 The procedure for configuring a node includes determining base features,
 applications to load at startup, and clustering and logical network view
 configurations, among others.

 If [node] isn't specified, the default target becomes \$OCI.
