Aggregate changes from multiple transactions in AsyncStore
----------------------------------------------------------

                 Key: ISPN-619
                 URL: https://jira.jboss.org/browse/ISPN-619
             Project: Infinispan
          Issue Type: Feature Request
          Components: Loaders and Stores
            Reporter: Sanne Grinovero
            Assignee: Manik Surtani
             Fix For: 5.0.0.BETA1


After debugging ISPN-618 we found out that the different changes of different transactions are not being coalesced in a smaller set of changes in the AsyncStore (see mailing list); we choose to solve ISPN-618 just fixing that bug, postponing the optimization idea as it would need more testing while ISPN-618 was found during CR3 testing.
The AsyncStore implementation should aggregate changes in a "transactions" variable in the same way as AbstractCacheStore, so to push only committed Modifications to the state-changes which are going to be async-applied to the delegated store.

So it seems to make sense to have AbstractDelegatingStore extend the AbstractCacheStore to inherit the same prepare/commit/rollback methods, but this affects all implementations of AbstractDelegatingStore.
