Add Deterministic Testing Infrastructure

[mikewcasale]

Enhancement Description

• Adds a deterministic testing infrastructure based on Tenderly testnets.

Rationale

• Existing tests often fail randomly due to reliance on a mainnet web3 connection, and they fail to cover many real-world scenarios. Therefore, a reliable test matrix across networks, exchanges, tokens, and arb-modes would be hugely beneficial to avoid regressions.

Impact Analysis

• Automated Tests: This is a massive enhancement to our automated tests.
• Risks: Difficult to get coverage of the "default" runtime parameters which only fetch the last 1000-2000 blocks, so we should be aware that regressions specific to this could still occur.
• Performance: Expected to increase the time required to run automated tests.
• Monitoring: None
• Logging: None
• Documentation: Some new documentation should be included which is specific to running these tests.
