Trading fee and Trade & Earn multiplier changes

Summary\nUpdate the trading fee and Trade & Earn multiplier of the following markets\nBackground\nAs part of the Mainnet v1.6, negative maker fee is now a feature supported on Injective. The purpose of negative maker fee is to incentivise traders to post liquidity to the order book. Improving the liquidity of Injective is one of the top requests of the community and this is a step towards achieving that. Meanwhile, in order to encourage takers to participate in markets that have negative maker fees, the Trade & Earn multiplier for both maker and taker should now be the same for these markets. Typically, for a market with a positive maker fee, Trade & Earn multiplier is usually higher for makers as a source of incentive. With negative maker fee, this is no longer required.\nProposal\nThis proposal would adjust the maker fee to -0.01%, taker fee to 0.1%, Trade & Earn maker multiplier to 1x and Trade & Earn taker multiplier to 1x for the following markets:\n- OSMO/USDT PERP\n- BNB/USDT PERP\n- STX/USDT PERP\n- ATOM/USDT PERP\n- SOL/USDT PERP\n- DOT/USDT\n- ATOM/USDT\n- XPRT/USDT\n- EVMOS/USDT\n- APE/USDT\n- LINK/USDT\n- GF/USDT\nThis proposal would adjust the maker fee to -0.01%, taker fee to 0.1%, Trade & Earn maker multiplier to 1.5x and Trade & Earn taker multiplier to 1.5x for the following markets:\n- INJ/USDT PERP\n- BTC/USDT PERP\n- ETH/USDT PERP\n- INJ/USDT\n- WETH/USDT\nLink to Discussion\nhttps://gov.injective.network/discussion/6047-update-the-trading-fee-and-trade-earn-multiplier-of-the-following-17-markets
