> As discussed in OAK-4808 B1 I would like to expose an extension point in form of SPI in DocumentNodeStore Journal handling. 
> Each component which needs to add a custom property to {{JournalEntry}} would provide a {{JournalPropertyService}}. This service would provide a {{JournalPropertyBuilder}} which would be used to accumulate the {{JournalProperty}}
> # For background write - {{JournalProperty}} would be read from {{CommitInfo}} and would be added to the builder. Upon background write cycle the builder would provide a string representation of the builder state which would be save as a property in {{JournalEntry}}
> # For background read - {{DocumentNodeStore}} would create builder for each service and would update them from string property value which are read from the JournalEntry
> {{DocumentNodeStore}} would lookup all {{JournalPropertyService}} via {{JournalPropertyServiceTracker}} and construct a {{JournalPropertyHandler}} which would manage the builder state
