This release fixes a bug where the outbound proxy could loop infinitely while handling errors on meshed HTTP/1 connections. This would typically cause proxies to be fail health checks and be restarted. Furthermore, the proxy now requires identity. Proxies will log an error and fail to start if identity is disabled. --- * dns: Avoid allocating in `Name::is_localhost` (linkerd/linkerd2-proxy#1303) * metrics: Implement FmtMetrics for Option (linkerd/linkerd2-proxy#1302) * tracing: simplify subscriber construction with `Box`ed layers (linkerd/linkerd2-proxy#1304) * Require identity configuration (linkerd/linkerd2-proxy#1305) * build(deps): bump thiserror from 1.0.29 to 1.0.30 (linkerd/linkerd2-proxy#1306) * build(deps): bump tower from 0.4.8 to 0.4.9 (linkerd/linkerd2-proxy#1308) * build(deps): bump trust-dns-resolver (linkerd/linkerd2-proxy#1311) * build(deps): bump actions/checkout from 2.3.4 to 2.3.5 (linkerd/linkerd2-proxy#1313) * dns-name: Remove `webpki` dependency (linkerd/linkerd2-proxy#1316) * build(deps): bump libc from 0.2.103 to 0.2.104 (linkerd/linkerd2-proxy#1315) * inbound: Add a box layer to reduce compile times (linkerd/linkerd2-proxy#1317) * Split cryptographic dependencies into a dedicated crate (linkerd/linkerd2-proxy#1307) * Fix an infinite loop when downgrading HTTP/2 errors (linkerd/linkerd2-proxy#1318)

This release fixes a bug where the outbound proxy could loop infinitely
while handling errors on meshed HTTP/1 connections. This would typically
cause proxies to be fail health checks and be restarted.
Furthermore, the proxy now requires identity. Proxies will log an error
and fail to start if identity is disabled.
