/**
 * This is a special implementation of the TenantDao that does not rely on caching (CacheControllerDispatcher is not injected and passed
 * to the EntitySqlDaoWrapperInvocationHandler. It only implements the set of operations that does not require caching:
 * - Only getXXX methods where there is no Cache annotation on the SqlDao method
 * - In addition excludes getById method, which are cached by EntitySqlDaoWrapperInvocationHandler
 * 
 * 
 * It is used from the TenantInternalApi so that caching of catalog, overdue, ... can be done at a higher level (catalog module, overdue module)
 * without causing guice dependency issues.
