[Frax] [FIP - 179] Add STG/FraxBP to FXS gauge controller

Author

Proposal

Continue to incentivize FraxBP pools by adding a FXS gauge for the STG/FraxBP Convex pool.

The staking token is a wrapped Convex staking position represented by an erc-20 that receives CRV and CVX rewards. This token can then be staked on a Frax Finance gauge to then also receive FXS rewards.

The wrapped staking position itself is an unmanaged trustless position and can be found on the Convex github at https://github.com/convex-eth/platform/blob/main/contracts/contracts/wrappers/ConvexStakingWrapperFrax.sol

Voting

• For: Add the STG/FraxBP pool to the FXS gauge controller as a staked Convex position.

• Against: Do nothing.
