Parameter change: Enable liquidity module circuit breaker

Recently, proposal #62 passed with strong support from the Cosmos Hub community. Following up with proposal #62, B-Harvest(now Crescent Team) submit this parameter change proposal to enable liquidity module circuit breaker. Upon passing of this proposal, only withdrawal of assets from LP will be available on Gravity DEX operating on Cosmos Hub. Other activities such as swap and deposit will be disabled. We advise former Gravity DEX users to withdraw coins from LP and return assets to each original chain. Withdrawal of LP from Gravity DEX is also available on Crescent. The IBC relayer service from Cosmos Hub to other chains will be provided by Crescent Team until the end of June, so there might be no operating IBC relayers after end of June. Also, we are happy to announce Crescent Network launch today. We warmly welcome Gravity DEX users into the new Crescent DEX with upgraded features and liquidity incentives: https://www.crescent.network
