To avoid disruption during cluster nodes rolling or scaling, it's desired to complement the maxUnavailable from the rolling strategy with a PodDisruptionBudget. This commit adds the respective PDB objects following the core components implementation to the `tap` and `tap-injector` deployments. It can be enabled with the enablePodDisruptionBudget helm chart value. Fixes linkerd#11248 Signed-off-by: Matias Charriere <[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!)

To avoid disruption during cluster nodes rolling or scaling, it's desired to complement the maxUnavailable from the rolling strategy with a PodDisruptionBudget.
This commit adds the respective PDB objects following the core components implementation to the
tap,tap-injector,webandmetrics-apideployments. It can be enabled with the enablePodDisruptionBudget helm chart value and are installed only if each of those components have more than 1 replica.Fixes #11248
Previous PR was close due inactivity (#11249), sorry about that.
As requested there, I added in this new PR PDBs for
webandmetrics-api.prometheushas only fixed 1 replica; so it doesn't really make sense to add a PDB for it.
