CaloRec: Move to retrieve CaloDetDescManager from CondStore, part 1

Walter Lamplrequested to merge
wlampl/athena:CaloRec_DetDescrMgr_CondStore1 into master

In this MR: Change CaloCellContainerFromClusterTool and CaloThinCellsByClusterAlg to retrieve CaloDetDescManager from CondStore

The last remaining client in this package is CaloTowerxAODAlgoBase. This one is tricky b/c is uses the CaloDetDescrManager to cache stuff in initialize. I suspect this algo is actually obsolete (replaced by CaloTopoTowerFromClusterMaker) but this is to be verified.
