Add config template for qemu.conf

Code Issues Proposed changes

Currently, qemu.conf is not tunable by OSA. However, the default
config file for qemu.conf is typically all comments and is
not frequently overwritten.
This patch enables deployers to deploy a custom /etc/libvirt/qemu.conf
config file by defining a dictionary qemu_conf_dict.
config_template plugin is not used because the qemu.conf file does
not have sections, thus putting values in [DEFAULT] is untested.
