Configure libvirt environment

The environment/setup role will:

• Install libvirt and any dependencies
• Configure and load the kvm module (and arch-specific kvm_intel or kvm_amd module)
• Configure the libvirt networks defined in the networks variable
• Whitelist the libvirt network bridges in /etc/qemu/bridge.conf (or equivalent file)

The environment/teardown role will:

• Remove whitelist entries from /etc/qemu/bridge.conf
• Destroy and undefine the libvirt networks

The cleanup role will not remote packages or attempt to undo the KVM configuration, because these things may have been configured prior to running the script and we do not want to break an existing environment.
