Open a head between Hydra core members and test out the new functionality

[v0d1ch]

Within a group of 3+ people, we want to open a head to validate thte incremantal commit feature scenarios manually:

• Can commit to an open Head
  • no matter what is currently available on L2 (also empty head)
• Can commit and immediately close with the same snapshot
• Can do multiple increments one after another
• Can do multiple commits and decommits in sequence as long as decommitted UTxO are consistent
• Can commit and decommit the same UTxO should result in the same open Head UTxO
• Cannot commit while another decommit is pending
• Cannot decommit funds you don't own
• Cannot commit funds you don't own
• Can decommit everything from the Head
• Can process L2 transactions of independent UTxO while commit is happening.
• Cannot commit same UTxO in two Heads
  • specially in presence of rollbacks (due to network partition)
  • possible interactively?
• Can close and fanout while commit is pending
  • i.e. when someone did not submit incrementTx
  • either funds did not get committed at all or reimbursed by fanout
  • possible interactively?.
