Adding the support for query targeting using a query target policy
------------------------------------------------------------------

                 Key: OPENJPA-1138
                 URL: https://issues.apache.org/jira/browse/OPENJPA-1138
             Project: OpenJPA
          Issue Type: New Feature
          Components: slice
    Affects Versions: 2.0.0
         Environment: Windows Vista, Eclipse3.4.2,  Maven 2.1.0, Java 1.6.0_13
            Reporter: Anurag Rai
             Fix For: 2.0.0


Slice gives us an abstraction for using horizontally partitioned databases. As of now we use
hints to set targets for a particular query if we want it to be fired on  particular Slices(partitions).
This method works fine but we need to have something which works from outside the user code
as in the case of distribution policy. If we have such a way we can externally set targets
without changing the code. Such targeting should be available for select and find.
