Add Incentive Matching to Prop 13 Model

I propose that we extend the model currently used for semi-automatic incentive adjustments to include an Incentive Matching program, where we match external incentives paid to liquidity pools on Osmosis. Such as the previous program by Akash, current one by E-Money, and proposed one by Juno https://juno.aneka.io/proposals/1\n\nUnder the current process, new pool creators are asked to create Text Proposals so that we can come to consensus about whether or not these pools should begin receiving Osmo incentives following the Prop 13 model and on-boarding process.\n\nUnder the proposed new process, pool creators would create Text Proposals asking for governance agreement to add the pools to the model, but also to match a certain amount of external incentives that they plan to provide. For an approved pool with external incentives, the model would set a minimum incentive share with Osmo to match the USD value of the external incentives.\n\nThese incentive matches would be decided by governance on a case by case basis, and should be limited to some overall % of Osmo Incentives. I propose that we start with a soft limit of 20% of incentives, so matching no more than ~400,000 USD per day of external incentives.\n\nI also propose that we begin by matching the external incentives currently being paid by E-Money to pools 461, and 482. As well as the proposed Juno incentives on pools 497, and 498. These external incentives amount to a total of ~36,000 USD per day, or 1.9% of incentives at current prices.\n\nIf this proposal is approved, we will begin using the new spreadsheet for regular adjustment proposals starting October 11th 2021, and these pools will have their external incentives at least matched.\n\nIf this proposal is not approved, we will continue with the Prop 13 model without matching. As Juno pools are already approved for incentives, they will begin on-boarding regardless of which outcome is decided here.\n\nCurrent Spreadsheet:\n\nhttps://docs.google.com/spreadsheets/d/15-b7o4QHY4SNE7Cw6MSZZ9Xxxbwca_hw4coLN9Y2ZFM/edit?usp=sharing\n\nProposed Spreadsheet:\n\nhttps://docs.google.com/spreadsheets/d/1ruG_ZypTPZ9myr2ov5atclfCNRTPGoMYbStYqnVcf1c/edit?usp=sharing\n\nThis spreadsheet implements the proposed changes. I have also reconstructed the layout somewhat for better readability, with Incentives as the page for overview reading, and PoolData for detailed reading of data or calculations. These changes do not change the functionality of the spreadsheet.\n\nDiscussion:\n\nhttps://commonwealth.im/osmosis/proposal/discussion/2152-proposal-incentives-matching-program
