      Description

      This JIRA is to add the preliminary code for the QJournalProtocol. This protocol differs from JournalProtocol in the following ways:

      • each call has context information indicating the epoch number of the requester
      • it contains calls that are specific to epoch number generation, etc, which do not apply to other journaling daemons such as the BackupNode

      My guess is that, at some point, we can merge back down to one protocol, but during the initial implementation phase, it will be useful to have a distinct protocol for this project.
