Smoke test with mithril

[ch1bo]

• Adds --use-mithril to hydra-cluster which makes it use mithril-client to download the cardano network state before starting cardano-node.

• Adds mithril-client to our development and CI shells.

• Adds integration tests to ensure that mithril-client is invoked correctly on all known networks.

A mithril-bootstrapped smoke test run on preview is here: https://github.com/input-output-hk/hydra/actions/runs/7540117340/job/20524247050

Not in scope / moved to red bin:

• Connection to cardano-node sometimes fails (too early?) https://github.com/input-output-hk/hydra/actions/runs/7541070906/job/20527001929

Transactions Costs

Sizes and execution budgets for Hydra protocol transactions. Note that unlisted parameters are currently using arbitrary values and results are not fully deterministic and comparable to previous runs.

• The minting policy hash is only usable for comparison. As the script is parameterized, the actual script is unique per Head.

End-To-End Benchmark Results

This page is intended to collect the latest end-to-end benchmarks results produced by Hydra's Continuous Integration system from the latest master code.

Please take those results with a grain of salt as they are currently produced from very limited cloud VMs and not controlled hardware. Instead of focusing on the absolute results, the emphasis should be on relative results, eg. how the timings for a scenario evolve as the code changes.

It would be nice if we can query these url's since I think I saw them change once.

Maybe NoMithril or DontUseMithril?
