The tcp endpoint stack requires that connectors return `io::Result`, but the connector mock uses Boxed error types. This change modifies the mocked connector to use io::Errors. We also improve re-exports from the linkerd_io module to reduce import boilerplate.

This release simplifies internals so that endpoint-forwarding logic is completely distinct from handling of load balanced services. The ingress-mode outbound proxy has been simplified to *require* the `l5d-dst-override` header and to fail non-HTTP communication. This ensures that the ingress-mode proxy does not unexpectedly revert to insecure communication. Finally, a regression was recently introduced that caused all proxy logs to be output with ANSI control characters. Logs are now output in plaintext by default --- * discover: replace `linkerd-channel` with `tokio-util` `PollSender` (linkerd/linkerd2-proxy#969) * replace `linkerd-channel` with `tokio-stream` (linkerd/linkerd2-proxy#970) * concurrency-limit: use `tokio-util`'s `PollSemaphore` (linkerd/linkerd2-proxy#968) * http: Do not fail fuzz tests when all IO is not read (linkerd/linkerd2-proxy#973) * transport: Fix orig-dst compilation on non-Linux targets (linkerd/linkerd2-proxy#974) * Update trust-dns to fix possible panic (linkerd/linkerd2-proxy#975) * addr: fix `to_http_authority` panic with IPv6 (linkerd/linkerd2-proxy#976) * outbound: skip logical stacks when no profile is discovered (linkerd/linkerd2-proxy#963) * split: change traffic splits to require a profile (linkerd/linkerd2-proxy#964) * inbound: only build profile route stacks when a profile is resolved (linkerd/linkerd2-proxy#966) * profiles: make receiver param in `route_request` non-optional (linkerd/linkerd2-proxy#967) * outbound: move target types into stack modules (linkerd/linkerd2-proxy#971) * outbound: only build logical stacks for profiles with logical addrs (linkerd/linkerd2-proxy#972) * app: inbound: add fuzzer (linkerd/linkerd2-proxy#977) * admin: Fail connections when HTTP detection fails (linkerd/linkerd2-proxy#979) * reduce error boilerplate with `thiserror` (linkerd/linkerd2-proxy#980) * app: inbound: fuzzer: generalise fuzzers and solve coverage build (linkerd/linkerd2-proxy#978) * admin: Assume meshed connections are HTTP/2 (linkerd/linkerd2-proxy#982) * chore: Fix deprecations on nightly (linkerd/linkerd2-proxy#983) * fuzz: Add logging to fuzz targets (linkerd/linkerd2-proxy#985) * fuzz: don't panic when the proxy closes the conn (linkerd/linkerd2-proxy#986) * Commit lock files for fuzzers (linkerd/linkerd2-proxy#984) * fuzz: allow client requests to fail (linkerd/linkerd2-proxy#989) * tower: update dependency to 0.4.7 (linkerd/linkerd2-proxy#990) * outbound: Make the Endpoint::logical_addr field optional (linkerd/linkerd2-proxy#991) * trace: explicitly disable ANSI terminal colors (linkerd/linkerd2-proxy#994) * ingress: Require the l5d-dst-override header (linkerd/linkerd2-proxy#992) * outbound: Do not support TCP-forwarding in ingress-mode (linkerd/linkerd2-proxy#995) * Decouple tcp forward stack from Endpoint target (linkerd/linkerd2-proxy#996) * Pickup linkerd-await wrapper in docker build (linkerd/linkerd2-proxy#999) * docs: Add fuzzing report (linkerd/linkerd2-proxy#1000) * tests: Use io::Error in mocked connector (linkerd/linkerd2-proxy#1001) * outbound: Decouple endpoint & logical stacks (linkerd/linkerd2-proxy#1002)
