Re-use contestation period as a deposit deadline

[v0d1ch]

Depends on #1700

Reuse contestation deadline as a deposit deadline. This is a follow-up from offchain incremental commits where we just used the current time as the deposit deadline. Now the contestation period is re-used as a deposit deadline and on top of that we provide information about it in the CommitRecorded server output.

End-to-end benchmark results

This page is intended to collect the latest end-to-end benchmark results produced by Hydra's continuous integration (CI) system from the latest master code.

Please note that these results are approximate as they are currently produced from limited cloud VMs and not controlled hardware. Rather than focusing on the absolute results, the emphasis should be on relative results, such as how the timings for a scenario evolve as the code changes.

Looks good! I assume the reason the golden output changes is because of the API type changes?

[v0d1ch]

yes, now we also provide the information about the deadline
