Enable Variant Curve AMO Strategies

Summary

Enable Curve AMO Strategies on curve.fi to farm existing pools that take 3CRV collateral (USDC, USDT, DAI).

Background & Motivation:

Curve's pool system has grown to be highly integrated with other defi assets, and offers attractive yields on stablecoins. As an example, Compound, Iron Bank, and the factory metapools allow for farming against 3CRV assets. The Frax Pool currently has over $30m in idle USDC deposits that may be lent out.

In an effort to deploy the existing USDC collateral, farming these Curve pools allows for the protocol to maintain competitive yields while being flexible enough to switch between the different pools. To facilitate this, various Curve AMOs may be deployed that target different curve pools and deposit USDC, staking the curve pool LP token respectively. The assets will be kept on the balance sheet, and the Frax Comptrollers may allocate the rewards towards FXS1559 buybacks upon strategic discretion.
