This release introduces substantial proxy improvements as well as
new observability and security functionality.
* CLI
* Added the `linkerd alpha stat` command, which uses the smi-metrics
API; the latter enables access to metrics to be controlled with RBAC
* Controller
* Added support for configuring service profile timeouts
`(x-linkerd-timeout)` via OpenAPI spec (thanks @lewiscowper!)
* Web UI
* Improved the Grafana dashboards to use a globing operator for Prometheus in
order to avoid producing queries that are too large (thanks @mmiller1!)
* Helm
* Improved the `linkerd2` chart README (thanks @lundbird!)
* Proxy
* Fixed a bug that could cause log levels to be processed incorrectly
