DATAJDBC-123 - MyBatis integration on DbAction level.

If MyBatis-spring is available and a SqlSessionFactory in the Application Context we look for matching mapped sql statements instead of using the default generated SQL.

Introduced DataAccessStrategy as a new abstraction level, operating on a single entity. JdbcEntityOperations only contain operations related to complete Aggregates. Thereby also solving DATAJDBC-132.

Integration tests ending in HsqlIntegrationTest will only get executed using HsqlDb.
