refactor: improve manager building on simulator

[glevco]

Acceptance Criteria

• Implement Simulator.create_artifacts()
• Change Simulator.create_peer() to receive a Builder, instead of receiving each builder argument and setting them
• Provide new Simulator.get_default_builder() for convenience, keeping the previous default behavior
• Add Builder.enable_full_verification() and Builder.disable_full_verification()
