Add a helper postInclude to disable file size limit (MC16d)
Add a helper postInclude to disable file size limit in production. The motivation are overlay+trigger+reco jobs which can run just fine with 10k events/job but hit the file size limit for the temporary files. As it seems to be impossible to just disable the limit, this file sets it to 150 GB.
Not urgent for reprocessing, but nice to have if we build another release.
