[PWGLF] Centrality in MC GEN and RECO with mcCentrality task

[lorber98]

• Centrality in MC GEN and RECO with mcCentrality task: centrEstimator configurable default with FT0M, since for FT0C, currently, there isn't a CCDB object.
• Remove cut on max radius for compatibility with other O-O analyses
• Add ConfigurableGroups for better readability

Hi @lorber98 ! The PR looks fine but I am not sure you should remove the centrEstimator configurable
If the ccdb object does not exist for the FT0C, I think it would be better to just focus on the FT0M or ask for FT0C MC centrality calibration
However, I thought that there was a MC centrality calibration for the FT0C in OO (at least, I can see that there are 2 objects in ccdb). Maybe @ercolessi has more information
Thank you very much!

Hi @romainschotter, thank you for the comment.
I ran some local tests and tried filling the FT0C histogram using the "fillFt0C" = true configurable in the mcCentrality.cxx task, but I encountered some errors, if I did everything correctly. Because of this, I decided to comment out the centrEstimator configurable to keep the code cleaner for now..
However, I will uncomment these lines immediately so that the code is ready to support the FT0C calibration object.
Thanks a lot for the review!
