[BIP-497] Enable plsRDNTV2/8020RDNTWETH Gauge with a 2% weight cap

PR with Payload

https://github.com/BalancerMaxis/multisig-ops/pull/669

Summary: This proposal enables a Balancer gauge for a plsRDNTv2/8020RDNTWETH LP stable pool on Balancer Arbitrum.

This pool is requested to have a gauge with a 2% weight cap until adoption proves it deserves higher in the gauge system. The plsRDNTv2 yield is autocompounded and tracked via a rate provider which will be used to maintain peg of the stablepool. This will permit plsRDNTv2 lockers to compound their DLP rewards into permalocked DLP, while swapping in and out of the locked position. The pool will be therefore be yield bearing and be designated as a core pool with the core infra 1.75x multiplier for ARB STIP incentives mentioned here

Protocol Description: Plutus is an Arbitrum-native governance aggregator aiming to maximize users’ liquidity and rewards while aggregating governance behind the PLS token. Plutus’ objective is to become the de-facto Layer 2 governance blackhole for projects with veTokens and the home of exotic liquid staking derivatives.

plsRDNTv2 is an index (4626) built on top of the Radiant dLP, a liquid staking derivative of the max-locked dLP token on Radiant.

Motivation: We believe having plsRDNTV2 - 8020RDNTWETH LP on Balancer represents a strong partnership between Plutus, Balancer and Radiant, leading to permanently locked liquidity and governance for Radiant and Balancer as plsRDNTv2 locks the underlying DLP, which lives on Balancer permanently.

This allows us to create a flywheel that will bring value through the following mechanisms:

1. Aura and veBAL holders through bribes
2. Balancer through permanently locked liquidity and fees
3. Plutus and Radiant users via the liquid staking derivative

Specifications:

1. Governance: Current 3/5 multisig is controlled by the team, eventually governance power will be decentralized to bPLS holders. https://arbiscan.io/address/0xa5c1c5a67Ba16430547FEA9D608Ef81119bE1876
2. Oracles: the plsRDNTv2 contract will have a getRate function, this is under review by the integrations team pending approval
3. Audits: No audit for plsRDNTv2 but using the same mechanism as plvGLP https://sourcehat.com/audits/PlvGLP/
4. Centralization vectors: Multisig will have significant control over the system, including changing params and fees
5. Market History: No history for plsRDNTv2, but the plsRDNTv1 lp currently lives on 0x3fb69d8720816a604487f2fd5813b72c15dd77ea which has market history here: https://dexscreener.com/arbitrum/0x3fb69d8720816a604487f2fd5813b72c15dd77ea
6. Value: This product will lead to permanently locked liquidity on Balancer that will earn fees, while also bringing value to the Aura and veBAL holders via bribes.

Pool: 0x451B0Afd69ACe11Ec0AC339033D54d2543b088a8

Gauge w/ 2% cap: 0xB66E8D615F8109cA52D47D9cB65Fc4edcF9c1342

Specification:

The Balancer Maxi LM Multisig eth:0xc38c5f97B34E175FFd35407fc91a937300E33860 will interact with the GaugeAdderv4 at 0x5DbAd78818D4c8958EfF2d5b95b28385A22113Cd and call the addGauge function with the following arguments: gauge(address):0xB66E8D615F8109cA52D47D9cB65Fc4edcF9c1342 gaugeType(string): Arbitrum

Additionally, this pool is requesting core pool status as per BIP-457
