As I and Salvatore get same conclusions. This isn't bug neutron and
nova. It should be tempest bug. I removed nova from affected projects.

** No longer affects: nova

Title:
  Race to delete shared subnet in Tempest neutron full jobs

Status in Tempest:
  New

Bug description:
  This seems to show up in several different tests, basically anything
  using neutron.  I noticed it here:

  http://logs.openstack.org/89/112889/1/gate/check-tempest-dsvm-neutron-
  full/21fcf50/console.html#_2014-08-14_17_03_10_330

  That's on a stable/icehouse change, but logstash shows this on master
  mostly.

  I see this in the neutron server logs:

  http://logs.openstack.org/89/112889/1/gate/check-tempest-dsvm-neutron-
  full/21fcf50/logs/screen-q-svc.txt.gz#_2014-08-14_16_45_02_101

  This query shows 82 hits in 10 days:

  message:"delete failed \(client error\)\: Unable to complete operation
  on subnet" AND message:"One or more ports have an IP allocation from
  this subnet" AND tags:"screen-q-svc.txt"
