Title:
  When neutron lbaas agent is not running, 'neutron lb*’ commands must
  display an error instead of "404 Not Found"

Status in octavia:
  Confirmed

Bug description:
  When neutron lbaas agent is not running, all the ‘neutron lb*’
  commands display "404 Not Found". This makes the user think that
  something is wrong with the lbaas agent (when it is not even
  running!).

  Instead, when neutron lbaas agent is not running, an error like
  “Neutron Load Balancer Agent not running” must be displayed so the
  user knows that the lbaas agent must be started first.

  The ‘ps’ command below shows that the neutron lbaas agent is not
  running.

  $ ps aux | grep lb
  $
