Execute new commondata generation in CI
Created by: Radonirinaunimi
Addresses https://github.com/NNPDF/nnpdf/issues/1457.
Remaining to do:
-
fail if the exit status of even one single filter is non-zero (which currently happens a lot) -
fail if there are modified and/or unstaged files in nnpdf_data/nnpdf_data/new_commondata
-
list all the changed commondata files in comments
