Save 10seconds when running NetworkSpec

[pgrange]

Depending on how the different Ouroboros servers are instantiated during the tests, the tests can take 0.3 seconds or 10.3 seconds. This is due to ipRetryDelay .

We add a threadDelay before trying to connect to other peer so that we give our own listen thread to be already listening... which seems fair.

To check before merging:

• CHANGELOG is up to date
• Up to date with master

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.

Cost of Abort Transaction

Some variation because of random mixture of still initial and already committed outputs.

Cost of FanOut Transaction

Involves spending head output and burning head tokens. Uses ada-only UTxO for better comparability.
