• Add Docker debug instructions to README.md

Tools were mentioned in #77

Hi @gaby,

Thank you for your contribution! Although, I would prefer to keep the default container image as lightweight as possible. Maybe we could add some instructions in the README instead to help people debug these situations.

Let me know your thoughts, otherwise I will close this PR after some time.

@tooryx The problem is without some of those tools in the image you will need to build your own tsunami container for debugging.

I could probably remove vi and iproute

[tooryx]

Could you not just inject yourself inside the container?

$ docker run -d --rm  --network="host" --name=tsunami -v "$(pwd)/logs":/usr/tsunami/logs frakman1/tsunami:latest --ip-v4-target=172.17.0.2
xxxxxxxx (the container id)
$ docker exec -it tsunami bash
# apt update && apt install -y vi {...}

[gaby]

@tooryx Yes that will work as long as you have internet access.

Adding a note to the readme should be enough. I will change the PR later today after work

[tooryx]

Thank you!

[gaby]

@tooryx Done, I tried to keep simple and concise

[tooryx]

Thank you @gaby! I added a small note
