RHEL5 host doesn't provide a qtree monitor command, thus
we should disable qtree check on this kind of host.

This patch benefits from the better error message when key is missing
in config params. Instead of custom handling of missing param it
uses params[] directly.

I modified those params, where I was 100% certain that they are
required and doesn't have default value:
 * val = params.get(..) followed by if not val: raise...
 * int(params.get(...))
 * params.get(...).split()
 * commands which require string (eg. session.cmd(params.get(...)))

I didn't test all the tests before and after in order to verify
possible typos but I used pylint before and after, watching for
new errors (code rate before and after).

* 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.

1) vm.create() have to force new params.
2) use data_dir instead of vm.root_dir for image absolute path

Used wrong path and thus didn't match image file names.

This is a solution for issue #108, reported by Gerd.

The test multi_disk was calling a full preprocess
from the test scope, which is quite dangerous, as
it messes with threads set by the virt tests infrastructure,
making the test runner to hang.

As the idea here is just to create the required disks
before the vm starts, call preprocess_image for all
the images in params.
