Support #6272: get flux files into dcache and use them from there in production
declare v4 flux files to sam and set locations on bluearc
reproduceMeta_fluxSamweb.py in CVS
has g4numi and v4 hardcoded in to speed it up
has to write meta to my personal area because i can't write to mnvnumi account but files are declared so ok.
Currently running over all flux files, should be done later today
