Replace 'shardVersion' field in splitChunk, from which we only access the epoch, with an 'epoch' field

      We're doing this for moveChunk in SERVER-25673.

      'shardVersion' in splitChunk holds the collectionVersion of the chunk being split. Rather than abusing the 'shardVersion' field that gets parsed and placed in OperationShardingState, send an 'epoch' field that splitChunk handles.
