[BIP-91] Temporarily Adjust Optimism Fee Split

For October, November, and December redirect Balancer's 50% share of Optimism fees back into growth incentives - either bribing or direct LM. Bribing for L2's is likely to be a negative ROI so I suggest doing direct LM but if people feel strongly about bribing we can only do that.

Our proposal for OP incentives stipulated that we must pair OP 1:1 with protocol fees. If Balancer agrees to forego their 50% share of fees we can instead take these funds, pair them 1:1 with OP, and use them to further our growth on Optimism. The idea would be that when Balancer starts taking their 50% fee again in January we'd stand to earn a lot more money because we took these three months and invested in growth.

To date, Optimism has sent $50,100 in fees to Balancer since launch - so this does not represent a large loss of income. It will probably not even be noticed realistically. But it can have a large impact on our growth at this critical time. We're working to secure aggregator support on the new boosted pools as without that we're earning almost zero in swap fees. We need every dollar of protocol fees we can get returned as incentives to ensure we can continue our growth trajectory.

Would love to hear any thoughts or feedback. Thanks everyone.
