[FIP 268] Add GRAI/FraxBP to FXS gauge controller

Author: MajeStyle, growth @ Gravita Protocol

Background:

Gravita is a borrowing platform based on Liquity that is focused on bringing interest-free borrowing to liquid staking token holders. Borrowing occurs by minting GRAI, the debt token of Gravita, which is burned when debts are repaid. Over-leveraged borrowers are liquidated via a stability pool, where GRAI holders can deposit.

Motivation:

Deep liquidity for GRAI helps both to stabilize the price and facilitate borrowers. GRAI price will be further stabilized in the future with a redemption mechanism similar to Liquity. However, the system functions much better if the redemption mechanism is rarely used. Sourcing liquidity between GRAI and stablecoins like FraxBP is the primary bottleneck to the growth of Gravita and will be where the majority of resources go for the foreseeable future. That will start with protocol revenues, then governance tokens when the token launches.
