fix not all disk listed issue, get cdrom drive letter with
utils_misc.get_winutils_vol();

1). update pre_command: used scsi_debug parm to add_host instead write
sys filesystem to avoid device create delay;

2). fix passthrough scsi device cache to writethrough to avoid fail to
open /dev/sg* when drive_cache=none; do this because /dev/sg* is
emulated by scsI_debug module, backend of these device is memery, open
with O_DRIECT is not supported;

3). removed useless import module 'qemu_monitor'

These tests will create some other format of image, so the
options for qcow3 would affect them.
To make these cases still work with qcow3 format, reset the
'image_extra_params' parameter in them.

This test needs to add as many disk as qemu can accept, so
the cdrom added globally is unnecessary.

For Linux guests we require 27 disk + 1 boot image. We have to start
assigning PCIs from 0x3 in order to have 1 slot for NIC.

It would be also possible to remove VGA and use 28 disks.

Current config generates 5 disks, because one is added by the test
logic. This can be workarounded by setting stg_image_num = 0 and
using old params or using stg_params instead (this patch).

This patch renames:
 * multi_disk.signal_repeat -> multi_disk.one_disk_repeat

Update:
 * multi_disk.max_disk Set different parameters for ide and
   virtio_blk.
 * Don't start VM in usb_multi_disk case, to save some time
   for starting/stoping the VM which booted by framework.

Fix signal_repeat variant to boot with the correct bootindex.

* max_disk must not have any usbs, otherwise there are not enough
  slots in PCI
* default image_boot = yes which generates in multi_disk test
  multiple disks with index = 1 and test failure. By forcing default
  value stg_image_boot = 'no' we can keep the default value (and index
  of image1) and let the other disk to have their own indexes.

A frequent request we've got from users is that the name
'kvm' makes assumptions that are not true for a lot of
the use cases of the test suite. Then let's rename
the subtest 'kvm' to 'qemu', making it more accurate.

For tests that are specific to one virt type, and are hosted on
that virt type directory, make the virt_test_type a non requirement
by auto generating it.

In order to have self describing tests, split the original
subtests.cfg in several per test files, and create subtests.cfg
out from this information.
