+ * \brief Perform correct ZSK and KSK rollover action and plan next one.
+ *
+ * For given zone, check keys in KASP db and decide what shall be done
+ * according to their timers. Perform the action if they shall be done now,
+ * and tell the user the next time it shall be called.
+ *
+ * This function is optimized to be called from KEY_ROLLOVER_EVENT,
+ * but also during zone load so that the zone gets loaded already with
+ * proper DNSSEC chain.

+ * \param ctx         Zone signing context
+ * \param flags       Determine if some actions are forced
+ * \param reschedule  Out: timestamp of desired next invoke
