* Add tenant-partitioned L2 caches (#2956) When `tenantPartitionedCache` is enabled, each tenant gets its own cache namespace (keys include the tenant id), improving cache-hit ratio by preventing cross-tenant key collisions. Refactor BeanDescriptorCacheHelp to abstract base class with two concrete subclasses: - BeanDescriptorCacheHelpFixed - static cache refs (original behaviour) - BeanDescriptorCacheHelpPartitioned - per-request Supplier<> lookup so the correct tenant-scoped cache is resolved on each access Fix background-thread invalidation: clear(name) in partitioned mode now scans all matching cache entries by key prefix rather than calling tenantProvider.currentId() which is null/wrong on background executor threads. Add SpiCacheManager.clearTenant(tenantId) to allow removal of all cache entries for a deactivated tenant, preventing unbounded memory growth in long-running multi-tenant deployments. Also load cache settings (cacheMaxSize, cacheMaxIdleTime, etc.) from application properties - these were previously missing from loadSettings(). * Fix versions in test-java16 --------- Co-authored-by: robin.bygrave <robin.bygrave@eroad.com>
