Add unit test to ensure the right NSEC3PARAM event is scheduled in 'dns_zone_setnsec3param()'. To avoid scheduling and managing actual tasks, split up the 'dns_zone_setnsec3param()' function in two parts: 1. 'dns__zone_lookup_nsec3param()' that will check if the requested NSEC3 parameters already exist, and if a new salt needs to be generated. 2. The actual scheduling of the new NSEC3PARAM event (if needed).
