A previous commit removed the original ovs-sandbox based OVN tutorial
because it became too outdated and difficult to maintain. However,
the use of ovs-sandbox for basic OVN development and testing is incredibly
useful, so we should provide at least basic documentation on how to use it.
This commit introduces a new and shorter document that shows how to use OVN
in ovs-sandbox. It provides a single sample configuration, as well as a
sample ovn-trace command.
