Upgrade stOSMO, stJUNO, and stSTARS Pools to Stableswap

This proposal is to upgrade the following constant product pools to the new stableswap pool type: stOSMO/OSMO (#833), JUNO/stJUNO (#817), STARS/stSTARS (#810).

The stableswap pool type is more suitable for these liquid staked derivative pools, as the two tokens in each pool are pegged.

The address “osmo1k8c2m5cn322akk5wy8lpt87dd2f4yh9afcd7af,” a multisig controlled by the Stride Foundation, will be used as the scaling factor governor for all three pools. That means that this address will be able to adjust the stToken : token ratio (i.e. peg) where liquidity is concentrated, which is necessary because the peg shifts as the stToken gains value against the token.

The swap fee for all three pools, which is currently 0.3%, will be reduced to 0.05%.

This is a signaling proposal. If approved by Osmosis governance, the pool upgrades will be bundled with the next Osmosis chain upgrade.
