Create Module for All-to-All Network Tests

Use iperf for all-to-all network tests. Base code on somthing vaguely like:

Client to OSD tests:
# !/bin/bash

for i in 8 9 10 11 12 13
do
val=$((62+$i))
pdsh -R ssh -w osd[$i] iperf -s -B 172.27.50.$val &
done
# !/bin/bash

for i in 0 1 2 3 4 5 6 7
do
for val in 70 71 72 73 74 75
do
pdsh -R ssh -w client[$i] iperf -c 172.27.50.$val -f m -t 60 -P 1 > /tmp/iperf_client${i}_to_${val}.out &
done
done
# !/bin/bash

for i in 8 9 10 11 12 13
do
val=$((62+$i))
pdsh -R ssh -w osd[$i] iperf -s -B 172.27.49.$val &
done
# !/bin/bash

for i in 8 9 10 11 12 13
do
for val in 70 71 72 73 74 75
do
pdsh -R ssh -w osd[$i] iperf -c 172.27.49.$val -P 1 -f m -t 60 -P 1 > /tmp/iperf_${i}_to_${val}.out &
done
done

The issue provides Bash examples using iperf and pdsh but names no target module, existing entry point, or tests. Start by inspecting the repository's current benchmark modules and test layout, then define how the client-to-OSD and OSD-to-OSD all-to-all runs should be represented; done means the module executes those test combinations and records their output.
