Update IBC Client for Cerberus

The Cerberus chain spent 1.5 weeks in halt due to the upcoming Dragonberry patch. Due to this halt, the IBC channel is currently in a frozen state. \n\n # Halt timing \n This issue was addressed by halting the chain and implementing further versions of the Cosmos SDK in Cerberus Testnet. Due to an unexpected further halt on the testnet, Cerberus restart was planned based on the original dragonberry patch (v2.0.1: https://github.com/cerberus-zone/cerberus). \n\n The detail on the halt: https://gist.github.com/windpowerstake/13091c0a20ef523428f46409f673cac2 \n The detail on the further steps/restart: https://gist.github.com/windpowerstake/96d839c68b2d652e4d6f7c4672927549 \n\n # Similar props: \n * https://www.mintscan.io/osmosis/proposals/258 \n * https://www.mintscan.io/osmosis/proposals/259 \n
