This edge release adds support for per-request Access Logging for HTTP inbound requests in Linkerd. A new annotation i.e. `config.linkerd.io/access-log` is added, which configures the proxies to emit access logs to stderr. `apache` and `json` are the supported configuration options, emitting access logs in Apache Common Log Format and JSON respectively. Special thanks to @tustvold for all the initial work around this! * Updated injector to support the new `config.linkerd.io/access-log` annotation * Added a new `LINKERD2_PROXY_ACCESS_LOG` proxy environment variable to configure the access log format (thanks @tustvold) * Updated service mirror controller to emit relevant events when mirroring is skipped for a service * Updated various dependencies across the project (thanks @dependabot)
