Online backup for Journal.

      Description

      Expose online backups for the Journal (vs HAJournal).

      I chased the code for the basic backup mechanism and this could be exposed without HA easily enough.

      Include an option to not gzip the file (easy) so the snapshots maybe immediately re-deployed if so desired.

      Note: Exposing the incremental tx log as well would be significantly trickier, but could be done (I've looked at this before
      - the snapshot manager and HALogNexus would both have to be pushed down to the Journal so this touches a lot of code). Without the TX logs the application is responsible for replaying any lost updates in the case of a failover.
