This PR addresses two issues:
- reduce the number of contexts supported by the host-interface by
default to 1, we are not using those at the moment, and hence
we now create fewer MPI_Win at the startup
- introduces a micro-sleep in RO progress engine in case there are no
pending requests. This leads significant performance improvements
observed for inter-node communication with THor2 NICs.
