* storage ops refactor: - create StorageOps class similar to other ops classes - init storages list in StorageOps, no longer require lookup up default storages via CrawlManager - convert all storage functions to members, add storageops to operator - remove unused params, ensure crawl exists for rollover restart - add env var to determine if using local minio to use correct endpoint URL * crawls /seeds endpoint: just return empty list if not a crawl (eg. upload) * crawlmanager: remove unused code, rename check_storage -> has_storage
