Allow running perf client and server within dockers

[stormshield-damiend]

Add a way to run perf_client and perf_server within two dockers with optional simulated latency.

To build the binaries and the docker, use :
build.sh

To launch the server, use :
./run-server.sh -l 10 -c -o

This will :

• simulate a latency of 10ms using Linux kernel QOS
• capture all packets using tcpdump inside the docker
• open the capture with wireshark using the dumped keys

To launch the client, use :
./run-client.sh -l 10

This will launch perf_client for 5sec with a simulated latency of 10ms (we will the have a RTT of 10ms).

/!\ For now the GSO is disabled otherwise wireshark is not capable of deciphering packets.

Maybe add set -eu to the shell scripts for robustness?

This gets further now, but still fails before doing any testing:

i will rebase the work as it is quite old and see if i also have the issue.
