[BIP-219] Enable bb-t-USD Gauge [Polygon]

Transaction Payload

Summary:
The Tetu Protocol has been actively building within the Balancer ecosystem, with tetuBAL serving as its primary Balancer-focused product.
Tetu wants to leverage boosted pool functionality by introducing the bb-t-usd composable pool which consists of 3 liner pools (bb-t-USDC, bb-t-DAI, bb-t-USDT)

The underlying tokens are USDC, DAI, and USDT. Those tokens will be partially invested in the TETU4626 vaults (USDC, DAI, USDT) to earn yield from dFORCE / MESH / AAVE optimized according to the market conditions.

Protocol Description:

Tetu is an asset management protocol that implements automated yield farming strategy for users.

Motivation:

The implementation of linear and boosted pools is gradually enhancing Balancer’s capacity to boost capital efficiency throughout the protocol. The robust boosted pool aligns with Balancer’s objective to offer a secure platform for LPs to access external yield sources while simultaneously ensuring efficient liquidity for swapping. This approach benefits both LPs and the DAO, generating yield
