see: * https://github.com/linkerd/linkerd2-proxy-api/releases/tag/v0.20.0 * linkerd/linkerd2-proxy-api#562 * linkerd/linkerd2-proxy-api#559 * linkerd/linkerd2-proxy-api#565 * #4537 * #4546 * #4544 this commit updates linkerd2-proxy-api, pulling in the latest release. aside from a slew of dependency updates, this new version most importantly includes changes to set the state for forthcoming load-balancing work. these new fields are marked with "todo" comments to indicate where future work in `linkerd-proxy-client-policy` in that vein will introduce future enum variants, fields, marshalling and validation, etc. this new version also includes an update to the most recent version of rand, which will allow us to properly update to the latest version of hickory-resolver without introducing breakage in our audit job in CI.
