MediumMisaligned incentives may encourage aberrant behaviorOpen

There are incentives `tip` and `chip` that are designed to encourage keepers to perform liquidations. However, given that there is a static component, `tip`, it might be possible in certain configurations that it is profitable for users to create unsafe vaults and liquidate it to receive the incentive, encouraging a highly aberrant behavior. This issue was also noted by the Maker team in [MIP45](https://forum.makerdao.com/t/mip45-liquidations-2-0-liq-2-0-liquidation-system-redesign/6352) under `MIP45c19 Incentive Farming`.
