Add ability to wrap InDet config in RecExCommon
This is off by default (tested locally with q221) so should not do anything yet.
But if you set the following preexec
jobproperties.InDetJobProperties.useNewConfig.set_Value_and_Lock(True), then RecExCommon will try to use the new InDetConfig in addition to the old. Step 2 would be to change the logic to only include the new if the flag is set. But for now, this allows us to detect differences.
