Osmosis v11 Upgrade

Osmosis v11 Upgrade\nThis is a proposal to do a software upgrade to the v11.0.0 software tag of the Osmosis codebase on block height 5432450, which is estimated to occur on Wednesday August 3rd, UTC 16:00. Block times have high variance, so please monitor the chain for more precise time estimates.\n\n## Upgrade Features\nThis upgrade adds the following features:\n\n### Minimum fee for messages\nImplements the ability for messages to be assigned a minimum fee, without which the transaction will fail.\nThis minimum fee is initially implemented on:\n* CreateGauge - 50 OSMO\n* AddToGauge - 25 OSMO\n\n### Governance proposal submission deposit\nSubmitting a governance proposal now requires a percentage of the deposit to be filled by the proposing wallet.\nThis is set with the governance parameter min_initial_deposit_percent and is initially implemented as 25%.\n\n## Getting Prepared for the Upgrade\nAs always, we recommend validators utilize 64GB of RAM. Since state migration is relatively negligible in this upgrade, it is likely possible to get away with less, but still not recommended. If you are unable to have 64GB of RAM, at a minimum have a total of 64GB of swap set to prevent out of memory errors.\nIf using cosmovisor, manually build & copy the osmosisd binary to /cosmovisor/upgrades/v11/bin/.\nIf not using cosmovisor, wait for your node to halt at the upgrade height, then install and run the v11.0.0 binary.\n\n## Details of Upgrade Time\nThe proposal targets the upgrade proposal block to be 5432450, anticipated to be on Wednesday August 3rd, UTC 16:00. This uses an average block time of 6.2043 seconds per block, derived from the Mintscan block explorer. Note that block times have high variance, so keep monitoring the time. See countdown here\nThe upgrade is anticipated to take approx 30 minutes, during which time, there will not be any on-chain activity on the network.\nIn the event of an issue at upgrade time, we should coordinate via the validators channel in discord to come to a quick emergency consensus and mitigate any further issues.
