Title:
  SecurityGroupExists error when booting multiple instances concurrently

Status in OpenStack Compute (Nova):
  Fix Released
Status in OpenStack Compute (nova) icehouse series:
  New

Bug description:
  If the default security group doesn't exist for some particular
  tenant, booting of a few instances concurrently may lead to
  SecurityGroupExists error as one thread will win the race and create
  the security group, and others will fail.

  This is easily reproduced by running Rally jobs in the gate.
