SDNVPN test cases failed in CI

JIRA: DOVETAIL-439

1. SDNVPN test cases run in CI failed, because the file
  /home/opnfv/repos/sdnvpn/sdnvpn/test/functest/config.yaml is empty.
2. copy the file userconfig/sdnvpn_config_testcase1/2/4/8.yaml
  to /home/opnfv/repos/sdnvpn/sdnvpn/test/functest/config.yaml in Functest container
