PR is mostly noise from bounded_vector to o2::itsmft::tracking::bounded_vector where a using decl. would have sufficed. This is fine I guess. See some comments below.
Changed the header include in AliceO2Group/QualityControl#2687

@shahor02 I think this can be merged

[shahor02]

What was the reason of ITStracking/TrackingConfigParam.h -> ITSMFTTracking/ITSTrackingConfigParam.h move? These params are still specific for ITS only right (and temporarily for the ALICE3).

I imagined that @mpuccio wants to template it for the MFT parameters but Max should confirm

[shahor02]

OK, merging, can be changed later, if needed.
