refstack client: manually running improvement

JIRA: FUNCTEST-758

1.python tempest_conf.py can generate a reference tempest.conf under /hom/opnfv/.../refstack_client
  this is based on "rally verify configure-verifier"
  surely, user can define his/her own tempest.conf by not using this
2.python refstack_client.py -c <tempest_conf_path> --testlist <testlist_file_path>
  if not given, will use default path, if file not exists, will have error
