New primary key is the following: * table (if `main`, leave it empty) * family * gateway * destination * metric (priority) There might be more ways we can improve this (probably gateway should be removed?), but this should be much better model to represent routes in the system. This was discovered in KubeSpan development (@Ulexus). Signed-off-by: Andrey Smirnov <andrey.smirnov@talos-systems.com>
