DATAJDBC-137 - Improve EntityInformation usage.

Moved to both the usage of the newly introduced PersistentEntity.isNew(…) and identifier lookups via PersistentEntity instead of using a custom EntityInformation implementation. JdbcRepositoryFactory now creates a PersistentEntityInformation, SimpleJdbcRepository simply works with a PersistentEntity.

Removed references to EntityInformation (a repository subsystem concept) from the template implementation. Removed BasicJdbcPersistentEntity and its tests entirely. JdbcAuditingEventListener is now using an IsNewAwareAuditingHandler.
