Report avg from processes latency

super-netperf script runs multiple netperf processes. Each process
provides average latency and P99 latency as output.
For reporting, this script calculates average from all of the
processes latency. Calculating P99 latency from all the P99
latencies is difficult in bash script. Instead we are calculating
average from all the P99 latencies similar to what ingress-perf
does.

So the report will have
1. Average of average latencies
2. Average of P99 latencies
