Enable Superfluid Staking on OSMO/MARS

This proposal is to enable Superfluid Staking on the OSMO/MARS (#907) pool on Osmosis. \n\n##Details\nOSMO/MARS is currently the 7th largest pool on Osmosis, with ~2,100,000 OSMO. At the current 50% discount rate, superfluid staking would allow a further ~1,050,000 OSMO to be used to secure the network through staking. \n\n## About MARS\nMars protocol is a Money Market and Credit protocol initially launched on Terra that has launched a Cosmos chain as the hub of its operations for the IBC network. Mars' first outpost operates on Osmosis as the home of the deepest liquidity across IBC and enable users to lend, borrow and earn against Mars governance gated credit lines. \n\nWebsite: https://marsprotocol.io/\n\n Commonwealth Thread: https://commonwealth.im/osmosis/discussion/9987-enable-superfluid-staking-on-osmomars
