Title:
  nova coverage create lots empty folders even with coverage extension
  disabled

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  with nova coverage extenstion disabled as a default behavior, we noticed that a lot of empty folders is created under /tmp folder. And also with each time the nova service reboot, it will create new directory with name like nova_coverage_*.  WIth time go by, there will be nubmer of the empty folders accumulated. 
   It is expected that no folder will be created when user is not triggering nova coverage-start.
