Title:
  FIP disassociation takes longer in non DVR test scenario

Status in neutron:
  Expired

Bug description:
  Problem description:
  With series of VM delete operation in openstack (4000 vms) with KVM compute nodes,  the VM instance goes into ERROR state.
  The error shown in Horizon UI is 
  "ConnectionFailed: Connection to neutron failed: HTTPConnectionPool(host='192.168.0.1', port=9696): Read timed out. (read timeout=30)"

  This happens because neutron takes more than 30 secs (actually around 80 secs) to delete one port, and nova sets the instance into ERROR state 'cz the default timeout of all neutron api(s) is set to 30 sec in nova.
  This can be worked around, by increasing the timeout to 120 in nova.conf. But this cannot be recommended as the solution.

  cat /etc/nova/nova.conf | grep url_timeout
  url_timeout = 120
