Prop 579: Create USDT Supercharged Pools

This proposal would create six new Supercharged Liquidity pools:

* USDC/USDT 0.05% Spread
* USDC/USDT 0.01% Spread
* ATOM/USDT 0.2% Spread
* ATOM/USDT 0.05% Spread
* OSMO/USDT 0.2% Spread
* OSMO/USDT 0.05% Spread

## Background
During the rollout period, the creation of Supercharged Liquidity pools is permissioned by governance as established in Proposal 532.

This proposal will end after the proposal to add USDT as a quote asset has been completed.

## Choice of Pools
The proposed pools should be the most impactful to gain USDT liquidity.
The USDC/USDT pairing provides a Stable/Stable pool, pairing the currently dominant stablecoin in the Cosmos, USDC, against the newly added native USDT.

The ATOM/USDT and OSMO/USDT pairings provide trading locations for Osmosis' most liquid volatile assets.

These pairings should quickly establish USDT liquidity for the most common routes.

The higher spread factors mirror the current spread factors used on Classic pools. The lower spreads will potentially be more efficient at collecting rewards for the same liquidity, as seen in other concentrated liquidity models. The addition of two levels of the spread factor will enable the market to decide where liquidity reward collection is optimal.

## About USDT
Launched in 2014, Tether was the first stablecoin issued and remains the most prevalent stablecoin in use across the crypto ecosystem.
USDT is now available natively on IBC chains via Tether’s contract deployment on Kava.
