tauRecTools: remove unused properties and member variables/functions
The property of container name are replaced by ReadHandleKey, thus not used any more. They are now removed.
We use three diferent property ( "CellCorrection", "AxisCorrection", and "VertexCorrection") to decide whether to perform the same operation, e.g. tau vertex correction of the cell. Now, only "VertexCorrection" is used.
Member variables/functions not used by the tool are also removed.
