This edge release contains everything required to get up and running with
multicluster. For a tutorial on how to do that, check out the
[documentation](https://linkerd.io/2/features/multicluster_support/).
* CLI
* Added a section to the `linkerd check` that validates that all
clusters part of a multicluster setup have compatible trust anchors
* Modified the `inkerd cluster export-service` command to work by
transforming yaml instead of modifying cluster state
* Added functionality that allows the `linkerd cluster export-service`
command to operate on lists of services
* Controller
* Changed the multicluster gateway to always require TLS on connections
originating from outside the cluster
* Removed admin server timeouts from control plane components, thereby
fixing a bug that can cause liveness checks to fail
* Helm
* Moved Grafana templates into a separate add-on chart
* Proxy
* Improved latency under high-concurrency use cases.
