This edge release changes the behavior of the CNI plugin to run exclusively in "chained mode". Instead of creating its own configuration file, the CNI plugin will now wait until a `conf` file exists before appending its configuration. Additionally, this change includes a bug fix for topology aware service routing. * Changed the CNI plugin installer to always run in 'chained' mode; the plugin will now wait until another CNI plugin is installed before appending its configuration * Fixed bug where topology routing would not disable while service was under load (thanks @MarkSRobinson!) * Introduced `logFormat` value to the multicluster `Link` Helm Chart (thanks @bunnybilou!)
