Change CacheStore.store() to return the previous value instead of void.
-----------------------------------------------------------------------

                 Key: ISPN-721
                 URL: https://jira.jboss.org/browse/ISPN-721
             Project: Infinispan
          Issue Type: Task
          Components: Core API
    Affects Versions: 4.2.0.Final
            Reporter: Trustin Lee
            Assignee: Trustin Lee
             Fix For: 5.0.0.BETA1


Cache.put(key, value) operation returns a previous value.  However, CacheStore.store() does not return a previous value but void.  To overcome the impedance mismatch, the current implementation calls CacheStore.load() to simply get the previous value.  CacheStore.store() could be improved to reduce this unnecessary round trip.
