ok, we are now cluster centric on the rpc calls, we need to remove all the < 7 rpc_versions from the slurm_accounting_storage.c

ok, changed some things to figure out which cluster we are talking to.  It appears we are almost ready to start testing

ok we build without any warnings.  I am sure nothing works quite right, but rollup, wckey, and usage should work fine.  usage should be threaded FYI.
