Is your feature request related to a problem? Please describe.

In certain conditions secret values must be periodically updated.

Describe the solution you'd like

Annotation+CRD field to specify cronjob-like pattern for regeneration schedule.

Describe alternatives you've considered

Currently (if I understand it correctly) cluster operator would need to create a controller/cronjob to annotate generated secrets to trigger a regeneration.

Additional context

None.
