This change adds python based qtest framework that can be used to run
qtests from within a virtual environment. A bash script creates the virtual
environment and then runs the python based tests from within that environment.
All dependent python packages are installed in the virtual environment using
pip module. QEMU python test modules are also available in the environment for
spawning the QEMU based VMs.
It also introduces QEMU acpi/smbios biosbits python test script which is run
from within the python virtual environment.
