Create vm with correct mac for boot_time test

Update the script to get disk names from command instead of the

disks changed.

Currently we still wait client thread to stop after effective test
finishes, it wastes of time. This patch directly killes the threads,
then client_thread.join() will return immediately.

netperf: collect host/guest sysinfo by custom-built scripts

User wants to collect sysinfo of host/guest, but different users
might have different requests, and many kinds of system might be
used. So I would like to use custom-built scripts to collect the
information that will make users happy.

User needs to add shell scripts to autotest/client/tests/virt/shared/scripts/,
and set the script path in config file.

eg:
 #log_hostinfo_script = scripts/rh_perf_log_hostinfo_script.sh
 #log_guestinfo_script = scripts/rh_perf_log_guestinfo_script.sh
 #log_guestinfo_exec = bash
 #log_guestinfo_path = /tmp/log_guestinfo.sh

Then the script output will be saved to $test.resultsdir/sysinfo,
analyzer can use 'diff' to compare the system information when
regression occurs.

I will send a pull request to add to example scripts to virt-tests repo.
