Bug description:
  Currently, only mysql and postgresql deadlock errors are properly handled.
  The error message for DB2 looks like:

  'SQL0911N  The current transaction has been rolled back because of a
  deadlock or timeout.  <deadlock details>'

  Olso.db needs to include a regex to detect this deadlock. Essentially the same as
      https://bugs.launchpad.net/nova/+bug/1270725
  but for DB2

  This is an example error:

  2014-07-01 19:52:16.574 2710 TRACE
  nova.openstack.common.db.sqlalchemy.session ProgrammingError:
