A previous commit removed the original ovs-sandbox based OVN tutorial because it became too outdated and difficult to maintain.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.
