add remap file to Run3 config to avoid overwriting locked container
PFRun3Config.py test job runs on an ESD which already has links defined in it. To avoid a locked container issue, remap the container using the Remapping service all of the writehandles to a new form.
Thanks

NB: this uses the new style Run3 config (e.g. Component Accumulators) so isn't the same as eflowRec/share/RemapItems.py)
