[BIP-439] Enable DUSD/4pool Stable Pool gauge on Optimism

PR with Payload

https://github.com/BalancerMaxis/multisig-ops/pull/526

Summary:

We request a gauge for the new DUSD/4pool stable pool on Optimism. This strategic move is intended to position the pool as the primary liquidity source for DUSD on Optimism, while simultaneously boosting DUSD liquidity on Balancer / BeethovenX. By channeling resources towards this specific pool, Davos Protocol aims to enhance liquidity and promote a vibrant ecosystem for both DUSD and within the Balancer ecosystem.

Protocol Description: Davos Protocol is a decentralized on-chain stablecoin protocol operating on various networks due to the omnichain capability of DUSD and is governed by the Davos Governance Token (DGT). It enables users to optimize the value of their crypto assets by accessing loans in DUSD stablecoin and earning competitive interest rates. The protocol prioritizes Liquid Staking Tokens (LSTs) as collateral, leveraging LSTs as a mechanism for scalable crypto yield. Through collateralized reward-bearing assets, particularly LSTs, users can compound their yields and benefit from DeFi composability. The protocol redistributes DUSD yield and incentives to stakers, lenders, and liquidity providers, amplifying the benefits and utility of LST tokens within the ecosystem. Community-driven governance by DGT token holders plays a vital role in decision-making and voting.

Motivation: Davos Protocol leverages its yield generation mechanisms to redistribute the generated yield as incentives, to the DEX pool. To streamline this process and improve efficiency, the protocol proposes for a gauge to be in place that enables direct distribution of these incentives. As the Total Value Locked (TVL) in the pool increases, the pool receives a larger portion of incentives from Davos Protocol. This incentivizes the pool to become the primary liquidity source for the DUSD omnichain stablecoin on Optimism.

Specifications:

1. Governance: Governance of the Davos Protocol is facilitated through DGT, granting holders the power to vote on protocol changes. DGT holders can propose and vote on modifications, ensuring democratic decision-making. Changes approved by the voters won’t take effect immediately, safeguarding the system against potentially harmful proposals. The Global Davos Council (GDC) is a council consisting of co-founders and advisors. The GDC serves as a governing body, providing guidance and expertise.
2. Oracles: As of now, the protocol does not rely on or utilize any oracles.
3. Audits: https://github.com/davos-money/davos-contracts/blob/main/audits/Quantstamp_130223.pdf https://github.com/davos-money/davos-contracts/blob/main/audits/Veridise_301122.pdf https://github.com/davos-money/davos-contracts/blob/main/audits/SlowMist_310523.pdf
4. Centralization vectors: DUSD operates as a decentralized stablecoin and the protocol is currently managed by the core team, but the Governance Token (DGT) and veDGT model will be released to enable community governance. Liquidation can be performed by any individual.
