Introduce index synchronisation between Containers in a DB
Database option INDEX_MASTER will turn on index synchronization between containers in a DB. Option value can be a conainter name or "", which means syncing to the biggest container (checked every commit).
Example usage:
SvcMgr.AthenaPoolCnvSvc.PoolAttributes += [ "DatabaseName = 'PoolFile1.root'; INDEX_MASTER = ''" ]
SvcMgr.AthenaPoolCnvSvc.PoolAttributes += [ "DatabaseName = 'PoolFile1.root'; INDEX_MASTER = 'POOLContainer(DataHeader)'" ]
Intended usage - combining container trees as friends
