Add TrackClonerWithClusters, modify CaloDigitCloner to support existing CaloAdc containers

1. Add TrackClonerWithClusters tool, which clones all VeloCluster and STCluster objects associated to a Track. This is required in Moore, in order for us to match the cluster cloning that's done in the Stripping.
2. Modify CaloDigitCloner to support cloning associated CaloAdc objects from existing containers, rather than always trying to create them from raw banks. This is required in Tesla, where we need to clone the ADCs that were created in Moore, without access to the raw information.
