Attempt to remove some MT locking and change the default for multi streams.

This merge request affects 2 packages:

• Control/AthenaServices
• Database/AthenaPOOL/AthenaPoolCnvSvc

Adding @ssnyder ,@mnowak as watchers

added Core Database master review-pending-level-1 labels

Hi @mnowak, this changes the default to use separate PersistentSvc for each output stream, as you suggested. It also removes some locks. I tested some of my multistream jobs, but please try to run your event sequencer (maybe post a recipe). In the meantime I'll mark this as 'WIP'. Thanks, Peter

Removing review label, since this is still WIP.

removed review-pending-level-1 label

It seems both multiple output streams and Event Service MT are working OK. Should be safe to accept.
Cheers, Marcin

Ok, if your ready for review, please resolve the WIP status.
