Add Fuse Pools as Yield Aggregator Strategies

Summary: The yield aggregator is at the centerpiece of Rari Capital, it is how we started. Let's enable it to begin to start directing capital into the Fuse pools that are safe.

Background: You can view Fuse here: https://app.rari.capital/fuse

Abstract: The yield aggregator currently has millions of dollars spread across the few pools. In the way that the aggregator rebalances between strategies like Compound, dYdX, etc--I propose that we add Fuse pools to this list. For the sake of this proposal, we will begin with Fuse Pools: 6, 7 & 8. This will enable us to decrease the risk, as the Rari Safety Score continues to evolve with time. The goal will work towards a future where the Rari Safety Score is the only variable in determining whether the yield aggregator can enter into a pool, but until then, the DAO will be charged with manually whitelisting the pools and using the safety scores as a metric to judge risk by. Additionally, it will enable us to trial how this works and ideally give lower rates to borrowers on Fuse and higher rates to the yield aggregator depositors. The pools that this should be activated on are: ETH pool, Stable Pool and Yield Pool.

This is the beginning of the Rari Capital flywheel that will enable us to offer something that very few other teams can offer. I'm super excited to be proposing this and I am excited to continue the conversation below.

A later proposal could increase the breadth of pools worked with and eventually move to the RSS completely.

Motivation: Enabling higher rates for yield aggregator users + lower rates for borrowers in Fuse.
