Supporting DUNE job submission

DUNE uses glideinWMS at FNAL and so should be able to support the same range of site types as CMS (i.e. everyone using CREAM or ARC and possible even HTCondor).

Details of the DUNE VO are in the GridPP Approve VOs list, and an RPM exists to install it. DUNE uses the CILogon OSG CA for production job submission, but some testing is done with user certificates from the CILogon Basic CA (these are normally hidden with the glideinWMS framework from the point of view of the CE.)

Supporting DUNE storage

This is currently being tested in the UK with DPM, dCache, and ECHO.
