Added CleanCache() method to the solver that deletes all the caches if the total size grows above a certain (configurable) limit (default: 500 MiB). The function is called externally to handle errors (usually log or ignore completely) and to avoid calling multiple times for multiple depsolves of a single request. The cleanup is extremely simple and is meant as a placeholder for more sophisticated cache management. The goal is to simply avoid ballooning cache sizes that might cause issues for users or our own services.
