Preparation to add additional proxy implementations.

(implement wait_proxy_sockets properly)

rmtree was only deleting directories but not files and sockets.

Especially important for large scale un-synchronized experiments

Includes an new DistributedExperiment class, a runner for distributed
experiments, a basic sequential runtime, and an example experiment
"dist_netperf" (although scaling beyond 2 hosts is currently still
broken in the rdma proxy).

Again prepration for distributed experiments.

preparation for remote execution, some directories need to be cleaned
up/created on the remote host some locally

With remote excution those sockets will be on the remote host

(preparation for remote commands)
