Discard TRD tracks with bad quality

[martenole]

The minimum number of TRD tracklets per track is configurable and set to 3. This avoids that e.g. ITS-TPC tracks are matched to a single tracklet (which is rather likely to be fake) and then don't have a chance anymore to be matched to TOF.
Also the minimum track quality can be specified, but before restricting this I would like to do some more tests. Therefore max chi2 value is set here to a very high value.

This also implies that downstream we will not have any TRD tracks with less than nTracketsMin tracklets, e.g. for vDrift calibration. But I think we are not using tracks with <= 2 tracklets in any case there so it should be no problem.

Thanks @martenole
but why not use existing GPUSettingsRecTRD ? In the end, the new params are in the same spirit as mTracker->Param().rec.trd.chi2StrictCut

[martenole]

True, I think I made it too complicated. I thought that this is not strictly a GPU setting, but still it belongs to the TRD reconstruction of course. So I will move it to the GPUSettingsList
