Enable cypress test to automate testing elasticsearch virtual service login

Currently there is script to test the elasticsearch endpoint (see script) using th ek8s service. Now that we have added virtual service, we should include testing the virtual service in addition to the k8s service endpoint so that any failures for virtual service will be noted in the package smoke test.

Also include elasticsearch virtual service to the big bang virtualservice.sh test <-- the virtualservice.sh automatically tests all virtual services that are deployed, so enabling the elasticsearch virtual service by default includes it in the testing.
