[ARFC] Repay Excess CRV Debt on Ethereum v2

From the technical side, as @Llamaxyz previously commented, we think the current model of swap is problematic when combined with timing, as the limits/caps go really easily out of control in a volatile (USDC/CRV) market.

At the same time, it is a bit concerning to see the stablecoins (USDC) cap to be spent raised to important levels, factually de-capitalizing the protocol. We think the community should probably re-evaluate using the aCRV holdings on the Collector, or even defining a streaming mechanism to, over time, use the aCRV income to close the bad debt.
If going this route, it could be an option to also “discount” from the variable borrow debt the equivalent to pending bad debt, to not generate any interest overhead, even if this involves some additional governance proposal.

Additionally, could be important to evaluate the swap based on other assets (non-USDC/stablecoins), with a more historic correlation with CRV. That way, the potential price exposure could be reduced.
