A0-4318: network flooding test

[fixxxedpoint]

Description

• An implementation of network flooding routines for both alephbft and substrate based networks. They try to flood all other nodes using some valid messages (messages are updated to newest available from normal protocol invocations).
• A dockerized nightly e2e-test that invokes the flooding routine for a single validator and checks if nodes were able to process a full session.

Type of change

Please delete options that are not relevant.

• New feature (non-breaking change which adds functionality)

Checklist:

• I have added tests

IMPORTANT: pipeline test result https://github.com/Cardinal-Cryptography/aleph-node/actions/runs/12051718872/job/33604011550

You can test it locally:

cargo build --package aleph-node --release --locked
docker build -t aleph-node:latest -f docker/Dockerfile .
cargo build --package aleph-node --release --locked --features network_flooding_test
docker build -t aleph-node:flooding -f docker/Dockerfile .
DOCKER_COMPOSE=docker/docker-compose_network_flooding_test.yml ./.github/scripts/run_consensus.sh

and watch net-out stats for Node3 using docker stats.

Thanks, I hate it.

Ugh, I kinda hate that our code now contains (optional) malicious parts within it. Nothing to do about it, just venting, resolve this comment.
