tests.unattended_install: Get qemu-img binary by utils_misc.get_qemu_img_binary()

Current code used to get qemu-img binary in unattended_install could not work
after tree splitting.
We already have utils_misc.get_qemu_img_binary(), so directly call it.

Fix setup_or_cleanup_iscsi error path

When the call will return "" (eg no iscsi_device found after 5 seconds),
we should clean up after ourselves and not expect the caller to clean
up after us.

skip numa pinning by checking cpus per node

We pin threads to each cpus in one node,
it's wrong to compare vcpus number with
node number.

numa: support to pin threads to extra node

In the past, we only try to pin threads to the cpus in one node.
If there is no enough nodes, we will try to pin a pair of vhost
thread and vcpu thread in same cpu. But if the number of vhost
threads isn't same as the number of vcpu threads, the pinning
isn't balanced.

This patch added support to pin threads to extra node.

redirect ssh debug message to /dev/null

The following commit added a '-vvv' option to ssh, then ssh will output
some debug message. If the debug message (like "debug2: channel 0:
window 999411 sent adjust 49165") mixes with the command output, it will
confuse Autotest aexpect, exceptions are raised in executing command.

This patch redirect the debug message to /dev/null, if the debug message
is needed, please save it to a file by another patch.
