TIP-117: Oracles, Roles, and OA Cleanup

This proposal performs various technical maintenance, cleanup and deprecation tasks. It also completes tasks from TIP-110 (https://tribe.fei.money/t/tip-110-simplify-pcv/4323) and deprecates the optimistic approval and ops timelocks, which as of FIP-82: Governance Enhancements (https://tribe.fei.money/t/fip-82-governance-enhancements/3945) are no longer required.

Specifically, it:

1. Deprecates old collaterization oracle caching Features :

   • collateralizationOracle is now read directly by pcvEquityMinter (buybacks) and tribeReserveStabilizer (backstop)
   • collateralizationOracleWrapper and collateralizationOracleWrapperImpl are no longer used anywhere in the system
   • collateralizationOracleGuardian (used to update the cache) is no longer used (revoked ORACLE_ADMIN_ROLE role)
   • collateralizationOracleKeeper (used to incentivize updates of the cache) is no longer used (revoked MINTER_ROLE role)

2. Removes empty or deprecated PCV deposits from the collaterization oracle:

   • DPI->DAI LBP swapper lenses
   • B.AMM LUSD Deposit (deprecated, would need to redeploy to use the new B.AMM)
   • Fuse pool 7 (Tetranode) LUSD deposit (0$ left)
   • Fuse pool 6, 19, and 24 FEI deposit (114$, 0$, and 6k$ left)
   • DAO Timelock lenses for agEUR and WETH
   • Curve/Convex d3 deposits (0$ left)
   • Withdraw remaining ETH/FEI liquidity from Uniswap v2 (0$ left)
   • Aave/Compound FEI/ETH deposits (0$ left)
   • Balancer FEI/WETH deposit (0$ left)

3. Unsets deprecated contracts from the safe addresses list, so funds can no longer be transferred to these deprecated contracts by the PCV Guardian

4. Implements components of TIP-110 Simplify PCV (https://tribe.fei.money/t/tip-110-simplify-pcv/4323):

• Move LM rewards (COMP, stkAAVE, CRV, CVX) to the TC Multisig where they can be sold.
• Move leftover RAI that is in PSM to the TC Multisig where it can be sold.
• Move LQTY to TC Timelock where it can be moved to a proper PCVDeposit later.

5. Deprecates the optimistic approval timelock by removing its various access roles. This is cleanup from FIP-82: Governance Enhancements (https://tribe.fei.money/t/fip-82-governance-enhancements/3945), the optimistic approval timelock is no longer required.

   • ORACLE_ADMIN ROLE
   • SWAP_ADMIN_ROLE
   • FUSE_ADMIN
   • PCV_GUARDIAN_ADMIN_ROLE
   • METAGOVERNANCE_GAUGE_ADMIN
   • PCV_MINOR_PARAM_ROLE
   • TOKEMAK_DEPOSIT_ADMIN_ROLE

6. Deprecates the ops optimistic timelock, which as of FIP-82: Governance Enhancements (https://tribe.fei.money/t/fip-82-governance-enhancements/3945), is no longer required. The following roles are removed:

   • METAGOVERNANCE_TOKEN_STAKING
