Title:
  [UI] Sahara should handle 100 response on row update

Status in OpenStack Dashboard (Horizon):
  Invalid
Status in Sahara:
  New

Bug description:
  I created cluster and was waiting while it is Active. After some time
  I observed in Sahara logs that cluster is already Active. In Horizon
  it was still in Starting state and didn't update. Here what I see in
  horizon logs:

  [12/Nov/2014 00:07:13] "GET /project/data_processing/clusters/?action=row_update&table=clusters&obj_id=e11d0970-2163-4521-92e3-25671087f633 HTTP/1.1" 200 1033
  [12/Nov/2014 00:07:15] "GET /project/data_processing/clusters/?action=row_update&table=clusters&obj_id=e11d0970-2163-4521-92e3-25671087f633 HTTP/1.1" 200 1033
  [12/Nov/2014 00:07:20] "GET /project/data_processing/clusters/?action=row_update&table=clusters&obj_id=e11d0970-2163-4521-92e3-25671087f633 HTTP/1.1" 100 0

  It looks like horizon stops updating cluster table row after 100
  response. I'm not sure why server responded 100, but this is
  definitely wrong behavior either of server side (must not respond with
  100 or should log why this happened) or client side (100 is a valid
  response and should not be treated as fatal error).

  Error from javascript log:
  Failed to load resource: net::ERR_EMPTY_RESPONSE http://localhost:8080/project/data_processing/clusters/?action=row_update&table=clusters&obj_id=e11d0970-2163-4521-92e3-25671087f633
