Fixes related to single-point-to-multi-point intents:

 * At the CLI level, the Ingress point argument should be specified
   before the Egress points arguments.
   This follows the natural Ingress/Egress argument ordering for
   other intents.
 * Added missing optional CLI complementer to shell-config.xml
