Optimize svc chain cases a bit

* Reduce some repeated nova/contrail api calls which were taking time
* and use the info present in VMFixture
* Remove some duplicate code while getting tap intf of a svm using vrf
* In create_service_vms(), create all svms in one-shot and verify them
* together, which brings down execution time
* In config_svc_chain(), no need to verify left and right vms when they
* are passed as args
