Title:
  Neutron client expects a VALUE for all TYPEs when creating a neutron
  lbaas pool  with session persistence

Status in OpenStack Neutron (virtual network service):
  Fix Released
Status in Python client library for Neutron:
  Fix Committed

Bug description:
  When creating a neutron lbaas pool with session persistence TYPE as "HTTP_COOKIE" or "SOURCE_IP" the VALUE field is not expected by the neutron server.
  1. If not given a VALUE, the client throws "the format expected is <TYPE>:<VALUE>" error.
  2. If given a VALUE, the server throws an internal server error.
  3. And in cases like this we should expect a 400 error instead of a 500 internal server error.

  I have pasted below the detailed log of the 2 different scenarios
  using HTTP_COOKIE.

  Case 1: If VALUE not given:
