changes to DQM harvesting

Change the Harvest job splitter to have two distinct modes, Periodic and EndOfRun that do not overlap.
In StdBase automatically add an additional EndOfRun DQM Harvest task if a Periodic DQM Harvest task is
specified. The EndOfRun task will trigger when the Periodic task is complete.

Store correctly the SizePerEvent and friends

Make sure that SizePerEvent is stored correctly in CouchDB and Oracle
if present, it goes in hand with RequestSizeFiles and RequestNumEvents
but these two are not really present in any request schema
so they will be always zero, only SizePerEvent is mandatory.

Also fix the clone and assign of requests pre-upgrade.
