[jira] [Created] (MAILBOX-373) Dead letter API + Contract + Memory default implemetation

Trần Tiến Đức created MAILBOX-373:
-------------------------------------

             Summary: Dead letter API + Contract + Memory default implemetation
                 Key: MAILBOX-373
                 URL: https://issues.apache.org/jira/browse/MAILBOX-373
             Project: James Mailbox
          Issue Type: New Feature
            Reporter: Trần Tiến Đức


From MAILBOX-372 :

 

When the EventBus maxRetry is exceeded on a MailboxListner execution is exceeded we will store it in the **EventDeadLetter**.

The goal of this ticket is to define this API in `mailbox/api`, propose its test contract and a default implementation, memory based, exposed in `mailbox/event/memory`.

Please note that it should have a `MultiMap<Group, Event>` structure: given a listener, give me the failed events.

This allows:
 - audit.
 - To schedule a redelivery (very usefull for instance when ElasticSearch is crashed)
