Title:
  create_security_group code may get into endless loop

Status in neutron:
  Fix Released
Status in neutron kilo series:
  Fix Committed

Bug description:
  That damn piece of code again.

  In some cases when network is created for tenant and default security group is created in the process, there may be concurrent network or sg creation happening.
  That leads to a condition when the code fetches default sg, it's not there, tries to add it - it's already there, then it tries to fetch it again, but due to REPEATABLE READ isolation method, the query returns empty result, as in the first attempt.
  As a result, such logic will hang in the loop forever.

  Reproducible with rally create_and_delete_ports test.
