Add network test in CI and run demo command (#1552)
<!-- Describe your change here --> This PR enhances the [demo tutorial](https://hydra.family/head-protocol/docs/getting-started/) by enabling `hydra-cluster` benchmarks to run on an active Hydra cluster. **usage** See the newly introduced `network-test.yaml` for the related invocations of pumba and the hydra clients. Supposing they are running, you simply run: ```sh nix run .#legacyPackages.x86_64-linux.hydra-cluster.components.benchmarks.bench-e2e -- \ demo \ --output-directory=$(pwd)/benchmarks \ --scaling-factor=100 \ --timeout=1000s \ --testnet-magic 42 \ --node-socket=${NETWORK_DIR}/node.socket \ --hydra-client=localhost:4001 \ --hydra-client=localhost:4002 \ --hydra-client=localhost:4003 ``` and you will get some statistics on txns confirmed, time taken, etc. **prerequisites** - A Cardano node must be running on specified `node-socket`. - Hydra nodes must be operational on provided `hydra-client` hosts. - There’s no need to pre-seed the keys, as the bench-demo script will automatically fund them using the faucet. - Note that the reference scripts should already be published, and the Hydra nodes must be running with those scripts. **Todo** - [x] Fix the `FIXME` about `> 33` - [x] Remove duplicate seeding - [x] Make sure the entire CI process doesn't fail when the pumba causes the network to fail - [x] Make it so that if it _fails_ the head is closed. - [x] Quick little matrix to run a few different scenarios - [x] Make the bench-e2e fail if it didn't submit all the txns ( ideally would also be able to see visually in the job list; but Github is missing a feature see also actions/runner#2347 ) - [x] Get docker info via `docker inspect` instead of parsing yaml (!) - [x] Make sure `results.csv` is written to the `outputDirectory` not the tmp directory - [x] Upload the results as part of the artifacts - [x] Write the summary out even when it failed --- <!-- Consider each and tick it off one way or the other --> * [x] CHANGELOG updated or not needed * [x] Documentation updated or not needed * [x] Haddocks updated or not needed * [x] No new TODOs introduced or explained herafter --------- Co-authored-by: Noon van der Silk <noon.vandersilk@iohk.io> Co-authored-by: Sebastian Nagel <sebastian.nagel@ncoding.at>
