[RORDEV-1481] New audit serializers, including fully configurable serializer

[mgoworko]

🚀New (ES) added new audit serializers - ReportingAllEventsAuditLogSerializer, ReportingAllEventsWithQueryAuditLogSerializer
🚀New (ES) There is an option to define custom audit serializer in config, without implementation
