DATAJPA-650, DATAJPA-655 - Moved attribute converters into distinct packages.

Keeping both the ThreeTen and JSR-310 JPA 2.1 attribute converters in a single package will make the use of packages-to-scan with Spring's EntityManagerFactoryBean rather difficult as all converters will end up being picked up by the persistence provider where both of them rely on optional project settings (Java 8 or ThreeTenBp on the classpath).

By moving them into separate packages, the classes can be used to point to packages without interfering with each other.
