Description

This PR aims to address this issue: https://github.com/IntersectMBO/cardano-node/issues/5600 With that aim, it adds two scenarios for automated DReps. This PR contains the first scenario:

Scenario 1

• Create default testnet with 3 DReps and 3 stake holders delegated, one to each DRep.
• Do some proposal and vote yes with the first DRep only.
• Check that proposal does NOT pass.
• Take the last two stake delegators and delegate them to "Abstain".
• Do some other proposal and vote yes with first DRep only.
• Check the new proposal passes now.
