Fix the load balancer service clients

The load balancer service clients were not using the base
service_client_config from tempest, so they would not pick up some
base settings, such as ca_certs, disable_ssl_certificate_validation,
etc.
This patch corrects that so that the clients will get the base
settings from tempest.
