The `--log-level` flag did not support a `trace` level, despite the underlying `logrus` library supporting it. Also, at `debug` level, the Control Plane components were setting klog at v=12, which includes sensitive data. Introduce a `trace` log level. Keep klog at `v=12` for `trace`, change it to `v=6` for `debug`. Fixes #11132 Signed-off-by: Andrew Seigner <[email protected]>

This stable release fixes a regression introduced in stable-2.13.0 which resulted in proxies shedding load too aggressively while under moderate request load to a single service ([#11055]). In addition, it updates the base image for the `linkerd-cni` initcontainer to resolve a CVE in `libdb` ([#11196]), fixes a race condition in the Destination controller that could cause it to crash ([#11163]), as well as fixing a number of other issues. * Control Plane * Fixed a race condition in the destination controller that could cause it to panic ([#11169]; fixes [#11193]) * Improved the granularity of logging levels in the control plane ([#11147]) * Replaced incorrect `server_port_subscribers` gauge in the Destination controller's metrics with `server_port_subscribes` and `server_port_unsubscribes` counters ([#11206]; fixes [#10764]) * Proxy * Changed the default HTTP request queue capacities for the inbound and outbound proxies back to 10,000 requests ([#11198]; fixes [#11055]) * CLI * Updated extension CLI commands to prefer the `--registry` flag over the `LINKERD_DOCKER_REGISTRY` environment variable, making the precedence more consistent (thanks @harsh020!) (see [#11144]) * CNI * Updated `linkerd-cni` base image to resolve [CVE-2019-8457] in `libdb` ([#11196]) * Changed the CNI plugin installer to always run in 'chained' mode; the plugin will now wait until another CNI plugin is installed before appending its configuration ([#10849]) * Removed `hostNetwork: true` from linkerd-cni Helm chart templates ([#11158]; fixes [#11141]) (thanks @abhijeetgauravm!) * Multicluster * Fixed the `linkerd multicluster check` command failing in the presence of lots of mirrored services ([#10764]) [#10764]: #10764 [#10849]: #10849 [#11055]: #11055 [#11141]: #11141 [#11144]: #11144 [#11147]: #11147 [#11158]: #11158 [#11163]: #11163 [#11169]: #11169 [#11196]: #11196 [#11198]: #11198 [#11206]: #11206 [CVE-2019-8457]: https://avd.aquasec.com/nvd/2019/cve-2019-8457/
