5.0.0

Notable changes

This release contains some notable changes. Please be careful to update your manifests according to the generated one.

• We upgraded to Kubebuilder V3
• We reviewed network disruption behavior to limit its impact on node level disruptions by targeting standard interfaces only (please read this doc about interfaces names)
• We added a safeguard (disabled locally) to never target the chaos-controller node to avoid breaking it and preventing a disruption to be removed by it (can be enabled or disabled through the controller configuration as described in the documentation linked just before)
