UI: Routes tab for Control Node does not show all routing instance

[Nischal Sheth]

The Routes tab for Control Node is broken - it doesn't show all routing
instances in the combo-box. Seems to show only the first page worth of
routing instances from Snh_ShowRoutingInstanceSummaryReq.

This happens because the output of Snh_ShowRoutingInstanceSummaryReq has
been paginated via bug 1475803.

Suggested fix is to build the entire list of routing instances by doing
successive Snh_ShowRoutingInstanceSummaryReqIterate based on next_batch
link in the output.
