**Motivation** See https://github.com/falcosecurity/event-generator/issues/86 **Feature** We basically need an option to allow the selection of a subset of actions. The associated rules maturity level (e.g., `stable`, `incubating`, `sandbox`) defines the subsets. **Alternatives** Do nothing. **Additional context** See https://github.com/falcosecurity/event-generator/issues/86
