Add convenient method `JpaRepository::clear` as companion of `flush` #3471

Sometimes we need to clear persistence context, especially for writing unit tests. We need to inject EntityManager before this commit, it is a bit inconvenient.

We do not want to mirror EntityManager API on the repository. Exposing the flush method already clutters the repository API and we do not want to continue in that way. We suggest implementing a repository fragment for your convenience.
