[ZIP-004] - Add ETHx/ETH Strategy to the ETH Omni Pool

Summary: ETHx is a liquid staking token from the company Stader. A detailed analysis has been conducted by the Llama Risk team: https://www.llamarisk.com/research/collateral-risk-ethx https://www.llamarisk.com/research/collateral-risk-ethx-addendum1

Motivation: The ETHx/ETH pair currently offers one of the highest yields on Curve, with a 13% APY on Convex. Rebalancing funds from frxETH and stETH/ETH to ETHx/ETH can significantly increase the yield on zunETH collateral without increasing risk.

Action:

• Add the ETHx/ETH strategy to the Zunami Protocol's ETH Omnipool strategies.
• Rebalance all funds from the frxETH and stETH/ETH strategies to ETHx/ETH.
