…or (#11649) Linkerd's control plane will skip webhook requests for resources in kube-system. The same configuration should be applied for other webhooks, i.e. tap and jaeger injectors. This change allows users to skip webhook on kube-system by default for tap and jaeger injector. Closes #11647 Signed-off-by: Takumi Sue <[email protected]>

This edge release introduces new configuration values in the identity controller for client-go's `QPS` and `Burst` settings. Default values for these settings have also been raised from `5` (QPS) and `10` (Burst) to `100` and `200` respectively. * Added `namespaceSelector` fields for the tap-injector and jaeger-injector webhooks. The webhooks are now configured to skip `kube-system` by default ([#11649]; fixes [#11647]) (thanks @mikutas!) * Added the ability to configure client-go's `QPS` and `Burst` settings in the identity controller ([#11644]) * Improved client-go logging visibility throughout the control plane's components ([#11632]) * Introduced `PodDisruptionBudgets` in the linkerd-viz Helm chart for tap and tap-injector ([#11628]; fixes [#11248]) (thanks @mcharriere!)

Currently the proxy-injector skips the kube-system namespace by default in its MutatingWebhookConfiguration namespaceSelector. We should do the same for the tap-injector and the jaeger-injector, whose selectors are currently empty. Although innocuous, this is currently generating a warning, in the Google Cloud Console for example (see https://linkerd.slack.com/archives/C89RTCWJF/p1700493518265689)
