simplify how we manage the cration/update of lcg stacks
Today we use only calls like ./utils/new_lcg_version.py --layer LHCB_7 105a @LCG_105a/platforms.txt
and we can avoid the boilerplate with some more structured description of the configuration we want, something like a YAML or JSON file lisling platforms, layers etc.
The idea is that one could just create/update the configuration file and say:
make 105a
(or equivalent).
