[Common] Centrality task: add PV mult. binning to histogram configurations

[ercolessi]

Hi @ddobrigk!

I’ve been asked to produce a calibration for the LF MC centrality for OO.
To do this, I’ll need some updates to the old centrality task (these histograms were not ported to the new multCent task).

Given the urgency (Alice Physics Week), I’d like to request these changes now if you agree. However, as we discussed previously, I am happy to chat on how to handle this more efficiently going forward. 🙂

Thanks a lot!

Hi @ercolessi, thanks, of course no objection - though note that the compiler is shouting due to some missing semicolons, I believe. Can you please take a look? I can approve once fixed. Then for the rest indeed at some point we should check how to best move forward :-)

Hi @ddobrigk indeed my apologies it was a silly mistake, thanks for the approval!
