ctdb-tests: Add some tests for 11.natgw eventscript

This includes adding support for:

* Configuring fake NATGW state in the eventscript unit tests

* "natgwlist" and "setnatgwstate" in ctdb command stub

* ip command stub to default to "main table" when no table specified,
  allow routes to be added without "dev" option (just add a default
  dev), support "metric" option
