[BIP-30] Purge Unused Gauges [second vote]

Motivation

Balancer currently has 50+ active gauges. The vast majority of these were grandfathered in when veBAL launched and many have never gotten votes. I propose to remove all gauges that meet both criteria below:

• Gets less than 0.1% of the vote
• 80/20 pool that is not the primary source of liquidity

Plus removing all gauges with exactly 0% of the vote unless recently approved in a gauge vote. These gauges are not likely to ever drive value to the protocol so there’s no reason to have them on the voting list. If desired, anyone can pursue a proposal to re-activate a gauge from this list in the future.

A full list of gauges to be killed:

• 80 THX / 20 USDC (Polygon)
• 80 GMX / 20 WETH (Arbitrum)
• 80 MTA / 20 WETH (Ethereum)
• 80 UNN / 20 WETH (Ethereum)
• 80 BANK / 20 WETH (Polygon)
• 80 VISION / 20 WETH (Polygon)
• 50 USDC / 50 WETH (Polygon)
• 80 SAND / 20 WMATIC (Polygon)
• USDC/TUSD/DAI/USDT stable (Polygon)
• USDC/FRAX/USDT/UST stable (Polygon)
• 33 AVAX / 33 WETH / 33 SOL (Polygon)
• 40 WMATIC / 40 MTA / 20 WETH (Polygon)
• 60 MCB / 40 WETH (Arbitrum)
• 80 GNO / 20 WETH (Arbitrum)
• DAI/USDT/USDC stable (Arbitrum)
• 80 TCR / 20 WETH (Arbitrum)
• 80 LINK / 20 WETH (Arbitrum)
• 80 MAGIC / 20 WETH (Arbitrum)
• 80 GRO / 20 WETH (Ethereum)
• 50 SILO / 50 WETH (Ethereum)
• 50 WETH / 50 USDT (Ethereum)

Specification

If approved, the DAO Multisig 0x10A19e7eE7d7F8a52822f6817de8ea18204F2e4f will interact with the AuthorizerAdaptor at 0x8F42aDBbA1B16EaAE3BB5754915E0D06059aDd75 and call performAction using 0xab8f0945 for the data(bytes) argument and the following list of contracts for the target(address) argument. Each contract will be its own transaction, thus there will be a total of 22 transactions.
