    Fixed Octavia tempest plugin

    * tempest init command calls oslo_config to generate sample tempest.conf
      which expects a list of tuples (group, [group_options]) provided by
      octavia plugin's get_opt_lists method. Due to comma at the end of
      service_option, oslo_config excepts one more tuple which was not there
      which causing failure to tempest init. Removing it fix the issue.

    * use register_opt for service_available in config
