During the process of implementing the libvirt test,
we've noticed that the whole mechanism implemented
by the KVM test (subtest loader, use of env file, params)
could be turned into common infrastructure. So move
all implementation to a class called virt_test.
We believe most virt test classes don't even need to be
implemented with this common infrastructure in place.
