Update expired client between Cosmoshub and Bostrom

This proposal will update the expired client on channel-240 between cosmoshub-4 and the bostrom networks. In turn, this will let users transfer from bostrom, and to transfer from cosmoshub back to bostrom.\n\nBy voting YES, the Cosmoshub stakers, voice their support to unfreeze IBC channel-240 between Cosmoshub and Bostrom.\n\nBy voting NO, the Cosmoshub stakers voice their dissent to unfreeze IBC channel-240 between Cosmoshub and Bostrom network.\n\nDetails:\n\nMost IBC connections between Bostrom and other Cosmos chains have been relayed, to a large extent, only by the Bro_n_Bro validator.\n\nOriginally, channel-240 was created with a very short trusting period of 2 days. Alas, the lack of monitoring from our side caused the expiration of client 07-tendermint-497, which in turn, led to the impossibility to transfer tokens using channel-240. Currently, there are around 710 ATOM stuck on the bostrom chain, belonging to about 20 different accounts.\n\nAs this might be the first case, when a channel renewal on cosmoshub-4, happens via a governance proposal, we have set up prior testing to ensure that everything will work smoothly. We also modified test-suite https://github.com/bro-n-bro/ibc-testbed (thanks to the Lum devs for the awesome repo), so everyone could simulate the client renewal using governance with this test suite.\n\nIn the case that this proposal goes through, client 07-tendermint-497 state will be substituted by the state of client 07-tendermint-643.\nAlso if passed - channels 240-5 (cosmoshub-4 - bostrom) would be used, only, to recover the stuck funds. New channels would be created with a longer trusting period to ensure further stability.\n\nWe will be happy to answer any questions at our Telegram community group or on our Discord.
