[BIP-47] Approve rETH as collateral for baoUSD and baoETH

Summary

Approve rETH as collateral for baoUSD and baoETH Vaults and Minter.

Background

rETH has has demonstrated strong performance in our risk assessments and has been identified as a good candidate to add as collateral for our synthetics. A comprehensive risk evaluation carried out by the llama risk team can be found here Llama Risk Evaluation of rETH

Proposed Solution

• Add rETH as Collateral:
  • Integrate rETH as a collateral option in the baoUSD Vault.
  • Integrate rETH as a collateral option in the baoETH Vault.
• Set Maximum Collateral Factor:
  • Establish a maximum collateral factor of 0.9 for both baoUSD and baoETH when using rETH.
• Minter Integration:
  • Approve rETH as a collateral option for the minter once it is operational.

Risks

• Market Volatility: rETH, being correlated to Ethereum, is subject to the fluctuations of the Ethereum market. High volatility could lead to significant liquidation events, affecting liquidity pools and potentially creating bad debt.
• Technical Dependencies: rETH's functionality is tied to the health of the Ethereum network and the correct operation of the staking protocol. Any disruptions or failures in these areas could impact rETH's stability and value.
