Some caveats: - This doesn't abide yet to the agreed API as declared in linkerd/linkerd2-proxy-api#388 . Instead, this is based on an earlier API proposal using "specifiers" to define the buckets keys. - The limiting logic has been added directly into the inbound http policy middleware. It relies on [governor](https://docs.rs/governor/latest/governor/). If we're not allowing to configure bursting in the first implementation, we might reconsider implementing something simpler directly ourselves. - There is actually an additional middleware (`RateLimitPolicyService`) that is currently commented out (used in the initial demo), that implemented a simpler approach, inspired by Tower's own rate-limiting middleware.
