The `cache` module has benchmarks, but they are not tested in CI and we don't really care about results -- the cache is basically just a HashMap. Let's just delete this unused benchmark.

There was a problem hiding this comment.
looks good to me — the build errors in rust-analyzer were getting annoying, and i think the cache implementation has gotten significantly simpler since these were written.

This release overhauls the discovery and routing logic implemented by the proxy: instead of looking at HTTP request metadata for service discovery, the outbound proxy now exclusively use each connection's target IP:PORT. This eager resolution eliminates per-request cache binding; and supports using TrafficSplit with non-HTTP services. This has a few side effects: - The `l5d-dst-override` header is no longer honored. - When the application attempts to connect to a pod IP, the proxy no longer load balances these requests among all pods in the service. The proxy will now honor session-stickiness as selected by an application-level load balancer. - `TrafficSplits` are only applied when a client targets a service's IP. - The proxy no longer performs DNS "canonicalization" to translate relative host header names to a fully-qualified form. --- * Unify RequestFilter and Admit middlewares (linkerd/linkerd2-proxy#692) * Only allow name-based profile discovery for inbound requests (linkerd/linkerd2-proxy#695) * outbound: initial tests for TCP mTLS (with fewer moving parts) (linkerd/linkerd2-proxy#693) * Stop honoring DESTINATION_GET_* configuration (linkerd/linkerd2-proxy#696) * stack: add SwitchReady service (linkerd/linkerd2-proxy#694) * telemetry: Remove trailing comma in build_info labels (linkerd/linkerd2-proxy#699) * Update Rust to 1.47.0 (linkerd/linkerd2-proxy#701) * cache: Delete benchmarks (linkerd/linkerd2-proxy#705) * outbound: Discover profiles for each unique TCP target (linkerd/linkerd2-proxy#704)
