This test case demonstrates how to manually configure an x86_64
guest to use the uefi-vars device, with the backing file for the
NVRAM residing on a remote location accessed via NBD.

It currently fails because the QEMU driver does not yet allow
the use of JSON for NVRAM. That will change in a future commit.
