Title:
  Adding a LBaaS VIP via horizon fails when the optional "Specify a free
  IP address from <my_subnet>" is not specified

Status in OpenStack Dashboard (Horizon):
  Confirmed

Bug description:
  Version
  =======
  Havan on rhel

  
  Description
  ===========

  I'm trying to add a VIP to my pool via horizon, I didn't specify the
  ip address (it's optional both in cli and horizon) because I wanted to
  be assigned with the next free ip address from my subnet
  automatically, however the whole operation of adding VIP fails with
  the following error:

  Error: Unable to add VIP "vlan_212_vip".
