This PR refactors the reports generation code. It removes RCR and CRCR crds and replaces them with AdmissionReport, ClusterAdmissionReport, BackgroundScanReport and ClusterBackgroundScanReport crds. The new reports system is based on 4 controllers: Admission reports controller is responsible for cleaning up admission reports and attaching admission reports to their corresponding resource in case of a creation Background scan reports controller is responsible for creating background scan reports when a resource and/or policy changes Aggregation controller takes care of aggregation per resource reports into higher level reports (per namespace) Resources controller is responsible for watching reports that need background scan reports I added two new flags to disable admission reports and/or background scan reports, the whole reporting system can be disabled if something goes wrong. I also added a flag to split reports in chunks to avoid creating too large resources.
