[GIP-103] Create GHO, USDT, DAI pools and adjust USDC pool limits

Over the past few weeks, the utilization of the USDC Gearbox pool has been close to 90%. Even despite 25%+ organic profitability (30% taking into account GEAR LM). One hypothesis is that users do not like to swap stablecoins into each other to provide liquidity and prefer to store them “as is”. Those USDT lovers are looking for USDT farms, USDC lovers are looking for USDC farms, DAI lovers are looking for DAI farms, etc. Therefore, it is proposed to create several additional avenues for the provision of stablecoins: USDT pool, DAI pool and GHO pool.

Specification

It is proposed to add initially only the most popular strategies on USDC pool:

• USDe,
• sUSDe,
• sDAI.

In the future, it will be possible to gradually add other strategies to the pools.

Other parameters are proposed to be set to the same as in the current USDC Pool. This list of parameters includes:

• Interest Rate Curve (check last numbers here )
• Quota Rates and Fees
• Liquidation Thresholds
• Credit Manager parameters.

Overall limit for Credit Manager is proposed to set at 10M GHO/USDT/DAI respectively.

Full configurations files can be found here (md5 checksum 23d7092be76388b16e19756e3a9f8f4d) . This is transactions details, that will be executed if the proposal is passed.

Adjusting limits for USDC

Tier 1 USDC Credit Manager is close reaching the maximum allowed limits (see GIP-97). Therefore, it is proposed to increase it: If current caps are full, limits for USDe can be increased by Timelock Controller and Technical Multisig up to 40M USDC as well as overall debt limit of Tier 1 Credit Manager - up to 65M USDC, without any further voting. Technical Multisig can do it gradually or one-time at its own discretion.
