Configure routing of MP template, using static routes.

Created RoutingConfiguration in VCPEmodel, which should hold routing configuration in Routers.

MProviderTemplate populates RoutingConfiguration with required static routes, as discussed in http://jira.i2cat.net:8080/browse/OPENNAAS-869.

MP Template builder configures desired static routes calling routers static route capability.

Default IP addresses have been changed, so lt links have a /30 subnet each one, and NetworkDomain IPRanges are correctly specified.
