Small smoke test fixes

[ch1bo]

• Added traces to give us more insights into when the smoke test fails (e.g. due to permission errors on the node.socket file)

• Fix permission of node.socket if it exists in smoke test workflow.

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.
