* Introduce Testcontainers as the mechanism to test against real data stores.
* Alter CI to handle running Testcontainers in reduced privilege mode.
* Run the data store specific test cases ONLY for the baseline Java 8 test execution.
See #2256.
When registered procedure output parameters, if the method annotated with @Procedure has a collection return type or an entity return type, then use ResultSet. Otherwise, handle either the array (Object[]) or the primitive types.
* Throw a proper exception when using an @Procedure-annotated method and no transaction is active.
* Introduce refCursor as a boolean flag to @Procedure denoting when to use REF_CURSORs for OUT parameters..
* Extract a ProcedureParameter command object to ease usage of a parameter's name, type and mode. (NOTE: javax.persistence already has "StoredProcedureParameter".)
NOTE: Integration testing of stored procedures is very limited by lack of HSQL's support for REF CURSORS. See ##2256 to track future work for potential testing against MySQL, Oracle, Postgres, or SQL Server.
See: #1959, #409.

Remove the @Repository annotation from interfaces in the examples, since it is not necessary on Spring Data interfaces (and creates a warning log anyway).
Closes#2234
Original pull request #2235
A few test that used reflection to access the actual SQL executed by a Query object failed with `java.lang.reflect.InaccessibleObjectException: Unable to make field protected java.lang.reflect.InvocationHandler java.lang.reflect.Proxy.h accessible: module java.base does not "opens java.lang.reflect" to unnamed module @1b9e1916`.
This change replaces the reflection used by a proper call to `unwrap`.

The dependency was seemingly introduced as a workaround to a Maven problem before this project even had the name Spring Data JPA.
No problems are noticeable when building without the dependency or when using it in a simple Spring Boot app without it.
Closes#2218
We introduced getRepositoryFragments(RepositoryMetadata,EntityManager,EntityPathResolver,CrudMethodMetadata) to easier get hold of typical arguments required for customization of repository base fragments that aren't bound to a specific entity type such as QuerydslJpaPredicateExecutor.
Closes#2202.
