Howard Pritchard 9955834ff1 pmix/cray: initial kvs removal work
Remove use of the Cray PMI KVS - which is designed for a lighweight
MPI that exchanges only a minimimal amount of connection info
(about 128 bytes per rank) - within cray/pmix.  Use Cray PMI
collective extensions instead.

This is the first of several steps to accelerate launch of
Open MPI on Cray systems using either native aprun or nativized
slurm.
