This is related to the section called "Adding a Gateway". Added workaround command for a known issue in networking-ovn. Even after the issue is resolved, it may be useful to have this in the tutorial, so folks have a feel for how OVN keeps track of chassis gateway. Also, removed redundant route command when assigning an address to the br-ex interface.
