Create digital pixel cluster on track tool configurable explicitly rather than cloning.
requested to merge goetz/athena:master_use_correct_pixel_lorentz_angle_in_digital_cluster_on_track_tool into master
When cloning the normal pixel cluster on track tool the Lorentz angle tool (private tool) is not cloned correctly. As a consequence the digital pixel cluster on track tool uses the default version of the SiLorentzAngleTool which uses SCT conditions data.
The problem is avoided by creating the configurable explicitly rather than cloning and modifying the normal pixel cluster on track configurable.
