Title:
  amphorae check fails because of empty string

Status in Nagios Charm:
  New

Bug description:
  I added a few prints in the code to show what is happening. Retrieving
  items["status"] fails because items is empty. That should be caught by
  the code instead of returning a traceback.

  
  sudo vi /usr/local/lib/nagios/plugins/check_octavia.py
  def check_amphorae(connection):

      """Check amphorae status."""

      lb_mgr = connection.load_balancer
      resp = lb_mgr.get("/v2/octavia/amphorae")

      print(resp)
      # python api is not available yet, use url
      if resp.status_code != 200:
          return [(NAGIOS_STATUS_WARNING, "amphorae api not working")]
   
      data = json.loads(resp.content)
      print(data)

      # ouput is like {"amphorae": [{...}, {...}, ...]}
      items = data.get("amphorae", [])
      print(items)

      # raise CRITICAL for ERROR status
      bad_status_list = ["ERROR"]
      bad_amp = [

          (
              NAGIOS_STATUS_CRITICAL,
              "amphora {} status is {}".format(item["id"], item["status"]),
          )
          for item in items
          if item["status"] in bad_status_list
      ]
