Add persistence property(s) to control detach state (particularly for JPA)

 Description  « Hide
When we detach with JDO we have the fetch-groups to define what is detached. While we also allow that for JPA, it would also make sense to allow a persistence-property route to define
1. "loaded" - just detach loaded fields
2. "all" - detach all fields (full object graph)
3. "fetch-groups" - using the fetch groups API

Added "datanucleus.detachedState" with possible values of "fetch-groups" (default), "all", "loaded". Also changed RetainValues to default to true for JPA (NUCJPA-141) to allow us to take advantage of "loaded" case
