Some more changes from @mvertens with updates for the NUOPC cap.
There's a new nuopc_cap_share directory added. SetVM is made public
in rof_comp_nuopc.F90 and some of the logging is slightly changed.
RtmIO is now using ROFID rather than instance name.
Also convert the nldas2 file into NetCDF5 format from Jim Edwards.
