--------------------------------------

Looks like fix for https://issues.apache.org/jira/browse/IGNITE-3471 will affect the same code. Need check if it is possible to fix IGNITE-3471 as part of this issue.

> In some cases user can't guarantee that EP behaves consistently on all nodes. In transactional cache this can lead to inconsistent cache, because we invoke EP on both primary and backup nodes.
> We can add {{withSendValueToBackup()}} flag (naming is arguable) which will override current default behavior.
> We also need to update documentation, especially provide the explanation of EP behavior in atomic and transactional caches.
