Title:
  Need clean up  ftp transfer faiure  in powervm driver

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  During spawn  with powervm driver , transfer  image file from  glance
  server to IVM host may fail in some conditions , like IVM host doesn't
  have enough disk space . It leaves the garbage file in IVM host , will
  disturb next spawn  after resovle envrioment  issue ,need clean it .

  In my test case I started an ISO deploy, then while the file was being copied to the IVM I filled up the destination directory to create an out-of-space condition. 
  The ftp transfer failed and the ISO was not deleted:
