dist: config file for distributed switch

Distributed gem5 is the result of the convergence effort between
multi-gem5 and pd-gem5. It relies on the base multi-gem5 infrastructure
for packet forwarding, synchronisation and checkpointing but combines
those with the elaborated network switch model from pd-gem5.
