* Change [implicit] Lazy loading to be by TYPE rather than by PATH We have some graph models where a common type (in the tests it is Label) is used in many different *paths* of the graph. When we are loading via *path* then all the loading of the Labels isn't in a single batch / load context but instead split into different load contexts PER PATH. This change, means that lazy loading operates by TYPE instead of by PATH. In the tests, all the Labels are read via a single lazy loading query rather that one lazy loading query per PATH, and this is more efficient. * ImmutableBeanCache part 1 * ImmutableBeanCache part 2 * ImmutableBeanCache part 3 - add ImmutableBeanCaches * ImmutableBeanCache - add propagation of caches to secondary queries * ImmutableBeanCache - use and improve BeanDescriptor.merge() to positional Using positional avoids the lookup by property name. * ImmutableBeanCache - add unit testing with BeanDescriptorMergeTest * ImmutableBeanCache - add testing for the further lazy loading on mutable beans Also add doc / guides * Add ImmutableCacheBuilder with underlying DefaultServerCache implementation This provides a cache with maxSize, maxIdleSeconds, maxSecondsToLive * Improve javadoc and doc / guides for ImmutableBeanCache * Add cache invalidation for ImmutableBeanCache * Use immutable cache direct hits for unmodifiable assoc-one refs - add ImmutableBeanCache.getIfPresent() as a non-loading probe - use immutable cache hits in AssocOneHelp / AssocOneHelpRefInherit - avoid creating ref beans and merge/copy for unmodifiable cache hits - keep existing mutable-query and miss/backfill behavior unchanged
