Creation of l3 router's external g/w snat SI breaks Contrail UI Service Instance Page

[Rahul]

After setting external g/w for a l3 router. The snat SI is created in old way with SI properties left/right interfaces instead of interface list.

But the Service Template for the snat sets interface types in its interface type list.

This breaks Contrail UI Service Instance page. The page doesn't load due to exception.
