[PIP-2] Approve the use of other AMM’s for nests liquidity

Currently we are using only Sushiswap for liquidity in minting our nests, This in itself is not an issue however coupled with the fact that we are the only one supplying and making a market for the liquidity for some of our synths to mint with is. For example, for nSTBL we currently make up all of the liquidity for RAI on Sushiswap, a majority of it coming from nDEFI-RAI.

This proposal aims to allow the galaxies to use any available AMM (Quickswap, Kyber, Curve, Uniswap) or aggregators (1inch) on Polygon to optimize the way the nests will acquire the necessary tokens, in an optimal way.

The first preference would go to start using the DEX aggregators 1inch, as we would be able to optimize our sources of liquidity and save on costs per mint by ensuring we have the best deals on Polygon for our underlying assets and in the case of RAI be able to capture more of it as it enters Polygon no matter what AMM it is, as it is a scarce token on this network. Also, this would benefit Polly in the long term because we wouldn’t be obligated to always create a market on Sushiswap for them.

The proposal will lead to the Smart Contract galaxy writing a different strategy of the nest to rely on dex aggregators or differents AMM on Polygon to acquire the underlying assets instead of solely rely on Sushiswap.
