[libvirt] [EXAMPLE PATCH 15/15] Example virt-admin

You had only one job.  That's what you can say about this example
binary.  In future, parts of virsh that are usable for this binary
should be split into separate shell-utils and virt-admin should gain all
the cool features of virsh without too much code addition.
