Alberto Garcia 7f65ce834a docs: document how to configure the qcow2 L2/refcount caches
QEMU has options to configure the size of the L2 and refcount
caches for the qcow2 format. However, choosing the right sizes for
a particular disk image is not a straightforward operation since
the ratio between the cache size and the allocated disk space is
not obvious and depends on the size of the cluster and the refcount
entries.

This document attempts to give an overview of both caches and how to
configure their sizes.
