Prop 628: USDC Quote Asset Resubmission

This is a resubmission of the parameter change in Proposal 624. The parameter targetted in proposal 624 was recently moved from the concentratedliquidity module to the poolmanager module and so the poolmanager module parameters also need updating to enable the use of USDC as a quote asset.

Quote Asset

Quote assets restrict the combinations of pairings possible in Supercharged Liquidity pools to improve routing as mentioned in Proposal 532.

Quote assets in use are (axl)USDC, USDT, DAI, WBTC, ETH, ATOM and OSMO.

This proposal would change the quote assets permission to use USDC IBC minted and transferred from Noble rather than the IBC hash of the USDC bridged from Ethereum via Axelar.

This causes all future pools using the USDC quote asset to use the native version on Osmosis. Existing pools are unaffected by this change as quote assets are validated only at the point of creation.
