Title:
  Baremetal pxe driver doesn't delete /tftpboot/{uuid}/*

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  Baremetal PXE driver deactivate_bootloader() is failing to delete tftp
  images when driver.destroy() is called. This results in a non-empty
  /tftpboot/{instance-uuid}/ directory being left behind on the compute
  node after an instance is deleted.

  I believe this happens because the instance parameter passed to
  driver.destroy() does not contain ['extra_specs']['deploy_kernel_id']
  or ['extra_specs']['deploy_ramdisk_id']. These these were passed to
  driver.spawn(), so I had assumed they were passed to driver.destroy()
  as well. This can be confirmed by logging the exception within the
  first try: block of deactivate_bootloader().

  One solution is to pass extra_specs to driver.destroy().
  Another solution is for deactivate_bootloader() to blindly delete all files under the /tftpboot/{instance-uuid}/ directory.
